Version 3.63 Nov 12, 2012 [SECURITY] - CR escaping for Set-Cookie and P3P headers was improved. There was potential for newline injection in these headers. (Thanks to anazawa, https://github.com/markstos/CGI.pm/pull/23) Version 3.62, Nov 9th, 2012 [INTERNALS] - Changed how the deprecated endform function was defined for compatibilty with the development version of Perl. - Fix failures in t/tmpdir.t when run as root https://github.com/markstos/CGI.pm/issues/22, RT#80659) - Made it possible to force a sorted order for things like hash attributes so that tests are not dependent on a particular hash ordering. This will be required in modern perls which will change the ordering per process. (Yves, RT#80659) Version 3.61 Nov 2nd, 2012 (No code changes) [INTERNALS] - formatting of CGI::Carp documentation was improved. Thanks to benkasminbullock. - un-TODO some tests in t/tmpdir.t that were passing in most cases. More on this: https://github.com/markstos/CGI.pm/issues/19# https://github.com/markstos/CGI.pm/commit/cc73dc9807b0fabb56b3cdf1a9726588b2eda0f7 Version 3.60 Aug 15th, 2012 [BUG FIXES] - In some caes, When unescapeHTML() hit something it didn't recognize with an ampersand and and semicolon, it would throw away the semicolon and ampersand. It now does a better job. of preserving content it doesn't recognize. Thanks to CEBJYRE@cpan.org (RT#75595) - Remove trailing newline after <form> tag inserted by startform and start_form. It can cause rendering problems in some cases. Thanks to SJOHNSTON@cpan.org (RT#67719) - Workaround "Insecure Dependency" warning generated by some versions of Perl (RT#53733). Thanks to degatcpan@ntlworld.com, klchu@lbl.gov and Anonymous Monk [DOCUMENTATION] - Clarify that when -status is used, the human-readable phase should be included, per RFC 2616. Thanks to SREZIC@cpan.org (RT#76691). [INTERNALS] - More tests for header(), thanks to Ryo Anazawa. - t/url.t has been fixed on VMS. Thanks to cberry@cpan.org (RT#72380) - MANIFEST patched so that t/multipart_init.t is included again. Thanks to shay@cpan.org (RT#76189) Version 3.59 Dec 29th, 2011 [BUG FIXES] - We no longer read from STDIN when the Content-Length is not set, preventing requests with no Content-Length from freezing in some cases. This is consistent with the CGI RFC 3875, and is also consistent with CGI::Simple. However, the old behavior may have been expected by some command-line uses of CGI.pm. Thanks to Philip Potter and Yanick Champoux. See RT#52469 for details: https://rt.cpan.org/Public/Bug/Display.html?id=52469 [INTERNALS] - remove tmpdirs more aggressively. Thanks to rjbs (RT#73288) - use Text::ParseWords instead of ancient shellwords.pl. Thanks to AlexBio. - remove use of define(@arr). Thanks to rjbs. - spelling fixes. Thanks to Gregor Herrmann and Alessandro Ghedini. - fix test count and warning in t/fast.t. Thanks to Yanick. Version 3.58 Nov 11th, 2011 [DOCUMENTATION] - Clarify that using query_string() only has defined behavior when using the GET method. (RT#60813) Version 3.57 Nov 9th, 2011 [INTERNALS] - test failure in t/fast.t introduced in 3.56 is fixed. (Thanks to zefram and chansen). - Test::More requirement has been bumped to 0.98 Version 3.56 Nov 8th, 2011 [SECURITY] Use public and documented FCGI.pm API in CGI::Fast CGI::Fast was using an FCGI API that was deprecated and removed from documentation more than ten years ago. Usage of this deprecated API with FCGI >= 0.70 or FCGI <= 0.73 introduces a security issue. <https://rt.cpan.org/Public/Bug/Display.html?id=68380> <http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-2766> (Thanks to chansen) [INTERNALS] - tmp files are now cleaned up on VMS ( RT#69210, thanks to cberry@cpan.org ) - Fixed test failure: done_testing() added to url.t (Thanks to Ryan Jendoubi) - Clarify preferred bug submission location in docs, and note that Mark Stosberg is the current maintainer. Version 3.55 June 3rd, 2011 [THINGS THAT MAY BREAK YOUR CODE] url() was fixed to return "PATH_INFO" when it is explicitly requested with either the path=>1 or path_info=>1 flag. If your code is running under mod_rewrite (or compatible) and you are calling self_url() or you are calling url() and passing path_info=>1, These methods will actually be returning PATH_INFO now, as you have explicitly requested, or has self_url() has requested on your behalf. The PATH_INFO has been omitted in such URLs since the issue was introduced in the 3.12 release in December, 2005. This bug is so old your application may have come to depend on it or workaround it. Check for application before upgrading to this release. Examples of affected method calls: $q->url(-absolute => 1, -query => 1, -path_info => 1 ) $q->url(-path=>1) $q->url(-full=>1,-path=>1) $q->url(-rewrite=>1,-path=>1) $q->self_url(); Version 3.54, Apr 28, 2011 No code changes [INTERNALS] - Address test failures in t/tmpdir.t, thanks to Niko Tyni. Some tests here are failing on some platforms and have been marked as TODO. Version 3.53, Apr 25, 2011 [NEW FEATURES] - The DELETE HTTP verb is now supported. (RT#52614, James Robson, Eduardo Ari�o de la Rubia) [INTERNALS] - Correct t/tmpdir.t MANIFEST entry. (RT#64949) - Update minimum required Perl version to be Perl 5.8.1, which has been out since 2003. This allows us to drop some hacks and exceptions (Mark Stosberg) Version 3.52, Jan 24, 2011 [DOCUMENTATION] - The documentation for multi-line header handling was been updated to reflect the changes in 3.51. (Mark Stosberg, ntyni@iki.fi) [INTERNALS] - Add missing t/tmpfile.t file. (RT#64949) - Fix warning in t/cookie.t (RT#64570, Chris Williams, Rainer Tammer, Mark Stosberg) - Fixed logic bug in t/multipart_init.t (RT#64261, Niko Tyni) Version 3.51, Jan 5, 2011 [NEW FEATURES] - A new option to set $CGI::Carp::TO_BROWSER = 0, allows you to explicitly exclude a particular scope from triggering printing to the browser when fatatlsToBrowser is set. (RT#62783, Thanks to papowell) - The <script> tag now supports the "charset" attribute. (RT#62907, Thanks to Fabrice Metge) - In CGI::Cookie, "Max-Age" is now supported for better spec compliance. (Mark Stosberg) [BUG FIXES] - Setting charset() now works for all content types, not just "text/*". (RT#57945, Thanks to Yanick and Gerv.) - support for user temporary directories ($HOME/tmp) was commented out in 2.61 but the documentation wasn't updated (Peter Gervai, Niko Tyni) - setting $CGITempFile::TMPDIRECTORY before loading CGI.pm has been working but undocumented since 3.12 (which listed it in Changes as $CGI::TMPDIRECTORY) (Peter Gervai, Niko Tyni) - unfortunately the previous change broke the runtime check for looking for a new temporary directory if the current one suddenly became unwritable (Peter Gervai, Niko Tyni) - A bug was fixed in CGI::Carp triggered by certain death cases in the BEGIN phase of parent classes. (RT#57224, Thanks to UNERA, Yanick Champoux, Mark Stosberg) - CGI::Cookie->new() now follows the documentation and returns undef if the -name and -value args aren't provided. This new behavior is also consistent with the docs and code of CGI::Simple::Cookie. (Mark Stosberg) - CGI::Cookie->parse() now trims leading and trailing whitespace from cookie elements as intended. The change also makes this part of the parsing identical to CGI::Simple::Cookie (Mark Stosberg) - Temp file handling was improved (RT#62762) [SECURITY] - Further improvements have been made to guard against newline injections in headers. (Thanks to Max Kanat-Alexander, Yanick Champoux, Mark Stosberg) [PERFORMANCE] - Make EBCDIC a compile-time constant so there's zero overhead (and less compiled code) in subroutines that test for it. (Tim Bunce) - If you just want to use CGI::Cookie, CGI.pm will no longer be loaded unless you call the bake() method, which requires it. (Mark Stosberg) [DOCUMENTATION] - quit referring to the <link> tag as being "rarely used". (Victor Sanders) - typo and whitespace fixes (RT#62785, thanks to scop@cpan.org) - The -dtd argument to start_html() is now documented (RT#60473, Thanks to giecrilj and steve@fisharerojo.org) - CGI::Carp doc are updated to reflect that it can work with mod_perl 2.0. - when creating a temporary file in the directory fails, the error message could indicate the root of the problem better (Peter Gervai, Niko Tyni) [INTERNALS] - Re-fixing https test in http.t. (RT#54768, thanks to SPROUT) - param_fetch no longer triggers a warning when called with no arguments (ysth, Mark Stosberg) Version 3.50, Nov 8, 2010 [SECURITY] 1. The MIME boundary in multipart_init is now random. Thanks to Byron Jones, Masahiro Yamada, Reed Loden, and Mark Stosberg 2. Further improvements to handling of newlines embedded in header values.

Workaround for a bug that appears in Apache2 versions through 2.0.54 in which SCRIPT_NAME and PATH_INFO are incorrect if the additional path_info contains a double slash. This workaround will handle the common case of http://mysite.com/cgi-bin/log.cgi/http://www.some.other.site/args, but will not handle the uncommon case of a ScriptAlias directive that adds additional path information to the end of the translated URI. Version 3.10, May 13, 2005 1. Added Apache2::RequestIO, which is necessary for mp2 interoperability. Version 3.09, May 5, 2005 1.

Version 3.06, Mar 09, 2005 1. Fixed bare call to script() in start_html 2. Moved Fh::DESTROY out of autoloaded functions so as to avoid clobbering $@ when CGI functions are executed in an eval{} context. 3. mod_perl 2.0 version detection patch in CGI::Cookie provided by Allen Day. 4. autoEscape() flag is now respected when generating extra attributes. 5. Tests for *tag start/end generation from Shlomi Fish. 6. Support for can() method provided by Ron Savage. 7. Fix for lang='' when outputting XHTML. 8. Added support for chunked transfer encoding, as suggested by Hakan Ardo 9. Fixed clobbering of row and column headers in tableized radio and checkbox groups, as reported by Nicolas Thierry-Mieg. 10. <Label> tags are now associated with form elements, as suggested by accessibility guidelines. 11. The <?xml> directive produced by start_html is now turned off by default and the charset is specified in a <meta> directive. Apparently IE6 (and maybe some versions of Opera) were getting confused by this. 12. Support for tab indexes. 13. Retired the HTML docs. The POD docs are now primary documentation. 14. CGI::Carp now correctly detects and handles Apache::Dispatch. 15. CGI::Util::utf8_chr now correctly sets the UTF8 flag on 5.006 or higher perls (fix courtesy Slaven Rezic).

Fixed incorrect results from end_form() when called in OO manner. 12. Fixed query string stripping in order to handle URLs containing escaped newlines. 13. During server push, set NPH to 0 rather than 1. This is supposed to fix problems with Apache. 14. Fixed incorrect processing of multipart form fields that contain embedded quotes. There's still the issue of how to handle ones that contain embedded semicolons, but no one has complained (yet). 15. Fixed documentation bug in -style argument to start_html() 16. Added -status argument to redirect(). Version 3.04, Jan 18, 2004 1. Fixed the problem with mod_perl crashing when "defaults" button pressed. Version 3.03, Jan 13, 2004 1.

Fixed bug in escapeHTML() which caused certain constructs, such as CGI->image_button(), to fail. 4. Fixed bug which caused strong('CGI') to fail. Be careful to use CGI::strong('CGI') and not CGI->strong('CGI'). The latter will produce confusing results. 5. Added upload() function, as a preferred replacement for the "filehandle as string" feature. 6. Added cgi_error() function. 7. Rewrote file upload handling to return undef rather than dieing when an error is encountered. Be sure to call cgi_error() to find out what went wrong. Version 2.46 1. Fix for failure of the "include" tests under mod_perl 2. Added end_multipart_form to prevent failures during qw(-compile :all) Version 2.45 1. Multiple small documentation fixes 2.

Too many screams of anguish at changed behavior of url(). Is now back to its old behavior by default, with options to generate all the variants. 2. Added regression tests. "make test" now works. 3. Documentation fixes. 4. Fixes for Macintosh uploads, but uploads STILL do not work pending changes to MacPerl. Version 2.41 1. url() method now includes the path info. Use script_name() to get it without path info(). 2. Changed handling of empty attributes in HTML tag generation. Be warned! Use table({-border=>undef}) rather than table({-border=>''}). 3.

Table and other HTML3 functions are now part of the :standard set. 6. Small documentation fixes. TO DO: 1. Do something about the DTD mess. The module should generate correct DTDs, or at least offer the programmer a way to specify the correct one. 2. Split CGI.pm into CGI processing and HTML-generating modules. 3. More robust file upload (?still not working on the Macintosh?). 4. Bring in all the HTML4 functionality, particular the accessibility features. Version 2.39 1. file uploads failing because of VMS patch; fixed. 2. -dtd parameter was not being properly processed. Version 2.38 I finally got tired of all the 2.37 betas and released 2.38. The main difference between this version and the last 2.37 beta (2.37b30) are some fixes for VMS. This should allow file upload to work properly on all VMS Web servers. Version 2.37, various beta versions 1. Added a CGI::Cookie::parse() method for lucky mod_perl users. 2. No longer need separate -values and -labels arguments for multi-valued form elements. 3.

File uploads from Macintosh versions of MSIE should now work. 23. Pragmas now preceded by dashes (-nph) rather than colons (:nph). Old style is supported for backward compatibility. 24. Can now pass arguments to all functions using {} brackets, resolving historical inconsistencies. 25. Removed autoloader warnings about absent MultipartBuffer::DESTROY. 26. Fixed non-sticky checkbox() when -name used without -value. 27. Hack to fix path_info() in IIS 2.0. Doesn't help with IIS 3.0. 28.

ReadParse() now returns a useful function result. 37. import_names() now allows you to optionally clear out the namespace before importing (for mod_perl users) 38. Made it possible to have a popup menu or radio button with a value of "0". 39. link() changed to Link() to avoid overriding native link function. 40. Takes advantage of mod_perl's register_cleanup() function to clear globals. 41. <LAYER> and <ILAYER> added to :html3 functions. 42. Fixed problems with private tempfiles and NT/IIS systems. 43.

Fixed a bug in which CGI objects created with empty string initializers took on default values from earlier CGI objects. 4. Documentation fixes. Version 2.27 1. Small but important bug fix: the automatic capitalization of tag attributes was accidentally capitalizing the VALUES as well as the ATTRIBUTE names (oops). Version 2.26 1. Changed behavior of scrolling_list(), checkbox() and checkbox_group() methods so that defaults are honored correctly. The "fix" causes endform() to generate additional <INPUT TYPE="HIDDEN"> tags -- don't be surpised. 2. Fixed bug involving the detection of the SSL protocol. 3. Fixed documentation error in position of the -meta argument in start_html(). 4. HTML shortcuts now generate tags in ALL UPPERCASE. 5. start_html() now generates correct SGML header: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN"> 6. CGI::Carp no longer fails "use strict refs" pragma. Version 2.25 1. Fixed bug that caused bad redirection on destination URLs with arguments. 2. Fixed bug involving use_named_parameters() followed by start_multipart_form() 3. Fixed bug that caused incorrect determination of binmode for Macintosh. 4. Spelling fixes on documentation. Version 2.24 1. Fixed bug that caused generation of lousy HTML for some form elements 2. Fixed uploading bug in Windows NT 3. Some code cleanup (not enough) Version 2.23 1. Fixed an obscure bug that caused scripts to fail mysteriously. 2. Fixed auto-caching bug. 3. Fixed bug that prevented HTML shortcuts from passing taint checks. 4. Fixed some -w warning problems. Version 2.22 1. New CGI::Fast module for use with FastCGI protocol. See pod documentation for details. 2. Fixed problems with inheritance and autoloading. 3. Added TR() (<tr>) and PARAM() (<param>) methods to list of exported HTML tag-generating functions. 4. Moved all CGI-related I/O to a bottleneck method so that this can be overridden more easily in mod_perl (thanks to Doug MacEachern). 5. put() method as substitute for print() for use in mod_perl. 6. Fixed crash in tmpFileName() method. 7. Added tmpFileName(), startform() and endform() to export list. 8. Fixed problems with attributes in HTML shortcuts. 9. Functions that don't actually need access to the CGI object now no longer generate a default one. May speed things up slightly. 10. Aesthetic improvements in generated HTML. 11. New examples. Version 2.21 1. Added the -meta argument to start_html(). 2. Fixed hidden fields (again). 3. Radio_group() and checkbox_group() now return an appropriate scalar value when called in a scalar context, rather than returning a numeric value! 4. Cleaned up the formatting of form elements to avoid unesthetic extra spaces within the attributes. 5. HTML elements now correctly include the closing tag when parameters are present but null: em('') 6. Added password_field() to the export list. Version 2.20 1. Dumped the SelfLoader because of problems with running with taint checks and rolled my own. Performance is now significantly improved. 2. Added HTML shortcuts. 3. import() now adheres to the Perl module conventions, allowing CGI.pm to import any or all method names into the user's name space. 4. Added the ability to initialize CGI objects from strings and associative arrays. 5. Made it possible to initialize CGI objects with filehandle references rather than filehandle strings. 6. Added the delete_all() and append() methods. 7. CGI objects correctly initialize from filehandles on NT/95 systems now. 8. Fixed the problem with binary file uploads on NT/95 systems. 9. Fixed bug in redirect(). 10. Added '-Window-target' parameter to redirect(). 11. Fixed import_names() so that parameter names containing funny characters work. 12. Broke the unfortunate connection between cookie and CGI parameter name space. 13. Fixed problems with hidden fields whose values are 0. 14. Cleaned up the documentation somewhat. Version 2.19 1. Added cookie() support routines. 2. Added -expires parameter to header(). 3. Added cgi-lib.pl compatibility mode. 4. Made the module more configurable for different operating systems. 5. Fixed a dumb bug in JavaScript button() method. Version 2.18 1. Fixed a bug that corrects a hang that occurs on some platforms when processing file uploads. Unfortunately this disables the check for bad Netscape uploads. 2. Fixed bizarre problem involving the inability to process uploaded files that begin with a non alphabetic character in the file name. 3. Fixed a bug in the hidden fields involving the -override directive being ignored when scalar defaults were passed. 4. Added documentation on how to disable the SelfLoader features. Version 2.17 1. Added support for the SelfLoader module. 2. Added oodles of JavaScript support routines. 3. Fixed bad bug in query_string() method that caused some parameters to be silently dropped. 4. Robustified file upload code to handle premature termination by the client. 5. Exported temporary file names on file upload. 6. Removed spurious "uninitialized variable" warnings that appeared when running under 5.002. 7. Added the Carp.pm library to the standard distribution. 8. Fixed a number of errors in this documentation, and probably added a few more. 9. Checkbox_group() and radio_group() now return the buttons as arrays, so that you can incorporate the individual buttons into specialized tables. 10. Added the '-nolabels' option to checkbox_group() and radio_group(). Probably should be added to all the other HTML-generating routines. 11. Added the url() method to recover the URL without the entire query string appended. 12. Added request_method() to list of environment variables available. 13. Would you believe it? Fixed hidden fields again! Version 2.16 1. Fixed hidden fields yet again. 2. Fixed subtle problems in the file upload method that caused intermittent failures (thanks to Keven Hendrick for this one). 3. Made file upload more robust in the face of bizarre behavior by the Macintosh and Windows Netscape clients. 4. Moved the POD documentation to the bottom of the module at the request of Stephen Dahmen. 5. Added the -xbase parameter to the start_html() method, also at the request of Stephen Dahmen. 6. Added JavaScript form buttons at Stephen's request. I'm not sure how to use this Netscape extension correctly, however, so for now the form() method is in the module as an undocumented feature. Use at your own risk! Version 2.15 1. Added the -override parameter to all field-generating methods. 2. Documented the user_name() and remote_user() methods. 3. Fixed bugs that prevented empty strings from being recognized as valid textfield contents. 4. Documented the use of framesets and added a frameset example. Version 2.14 This was an internal experimental version that was never released. Version 2.13 1. Fixed a bug that interfered with the value "0" being entered into text fields. Version 2.01 1. Added -rows and -columns to the radio and checkbox groups. No doubt this will cause much grief because it seems to promise a level of meta-organization that it doesn't actually provide. 2. Fixed a bug in the redirect() method -- it was not truly HTTP/1.0 compliant. Version 2.0 The changes seemed to touch every line of code, so I decided to bump up the major version number. 1. Support for named parameter style method calls. This turns out to be a big win for extending CGI.pm when Netscape adds new HTML "features". 2. Changed behavior of hidden fields back to the correct "sticky" behavior. This is going to break some programs, but it is for the best in the long run. 3. Netscape 2.0b2 broke the file upload feature. CGI.pm now handles both 2.0b1 and 2.0b2-style uploading. It will probably break again in 2.0b3. 4. There were still problems with library being unable to distinguish between a form being loaded for the first time, and a subsequent loading with all fields blank. We now forcibly create a default name for the Submit button (if not provided) so that there's always at least one parameter. 5. More workarounds to prevent annoying spurious warning messages when run under the -w switch. -w is seriously broken in perl 5.001! Version 1.57 1. Support for the Netscape 2.0 "File upload" field. 2. The handling of defaults for selected items in scrolling lists and multiple checkboxes is now consistent. Version 1.56 1. Created true "pod" documentation for the module. 2. Cleaned up the code to avoid many of the spurious "use of uninitialized variable" warnings when running with the -w switch. 3. Added the autoEscape() method. v 4. Added string interpolation of the CGI object. 5. Added the ability to pass additional parameters to the <BODY> tag. 6. Added the ability to specify the status code in the HTTP header. Bug fixes in version 1.55 1. Every time self_url() was called, the parameter list would grow. This was a bad "feature". 2. Documented the fact that you can pass "-" to radio_group() in order to prevent any button from being highlighted by default. Bug fixes in version 1.54 1. The user_agent() method is now documented; 2. A potential security hole in import() is now plugged. 3. Changed name of import() to import_names() for compatibility with CGI:: modules. Bug fixes in version 1.53 1. Fixed several typos in the code that were causing the following subroutines to fail in some circumstances 1. checkbox() 2. hidden() 2. No features added New features added in version 1.52 1. Added backslashing, quotation marks, and other shell-style escape sequences to the parameters passed in during debugging off-line. 2. Changed the way that the hidden() method works so that the default value always overrides the current one. 3. Improved the handling of sticky values in forms. It's now less likely that sticky values will get stuck. 4. If you call server_name(), script_name() and several other methods when running offline, the methods now create "dummy" values to work with. Bugs fixed in version 1.51 1. param() when called without arguments was returning an array of length 1 even when there were no parameters to be had. Bad bug! Bad! 2. The HTML code generated would break if input fields contained the forbidden characters ">< or &. You can now use these characters freely. New features added in version 1.50 1. import() method allows all the parameters to be imported into a namespace in one fell swoop. 2. Parameters are now returned in the same order in which they were defined. Bugs fixed in version 1.45 1. delete() method didn't work correctly. This is now fixed. 2. reset() method didn't allow you to set the name of the button. Fixed. Bugs fixed in version 1.44 1. self_url() didn't include the path information. This is now fixed. New features added in version 1.43 1. Added the delete() method. New features added in version 1.42 1. The image_button() method to create clickable images. 2. A few bug fixes involving forms embedded in <PRE> blocks. New features added in version 1.4 1. New header shortcut methods + redirect() to create HTTP redirection messages. + start_html() to create the HTML title, complete with the recommended <LINK> tag that no one ever remembers to include. + end_html() for completeness' sake. 2. A new save() method that allows you to write out the state of an script to a file or pipe. 3. An improved version of the new() method that allows you to restore the state of a script from a file or pipe. With (2) this gives you dump and restore capabilities! (Wow, you can put a "121,931 customers served" banner at the bottom of your pages!) 4. A self_url() method that allows you to create state-maintaining hypertext links. In addition to allowing you to maintain the state of your scripts between invocations, this lets you work around a problem that some browsers have when jumping to internal links in a document that contains a form -- the form information gets lost. 5. The user-visible labels in checkboxes, radio buttons, popup menus and scrolling lists have now been decoupled from the values sent to your CGI script. Your script can know a checkbox by the name of "cb1" while the user knows it by a more descriptive name. I've also added some parameters that were missing from the text fields, such as MAXLENGTH. 6. A whole bunch of methods have been added to get at environment variables involved in user verification and other obscure features. Bug fixes 1. The problems with the hidden fields have (I hope at last) been fixed. 2. You can create multiple query objects and they will all be initialized correctly. This simplifies the creation of multiple forms on one page. 3. The URL unescaping code works correctly now.
