7089 alphanumeric characters, CGI.pm removes this restriction by escaping
7172 It's possible for CGI.pm scripts to write into several browser panels
7186 in CGI.pm, but the HTML is very simple to write.  
7203 CGI.pm it looks like this:

7355 CGI.pm has limited support for HTML3's cascading style sheets (css).
7709 CGI.pm supports NPH scripts with a special NPH mode.  When in this
7710 mode, CGI.pm will output the necessary extra header information when
7715 version 2.30, CGI.pm will automatically detect when the script is
7737 Call B<nph()> with a non-zero parameter at any point after using CGI.pm in your program.
7751 CGI.pm provides four simple functions for producing multipart

7822 A potential problem with CGI.pm is that, by default, it attempts to
7825 megabytes.  CGI.pm will attempt to read the entire POST into a
7830 Another possible attack is for the remote user to force CGI.pm to
7831 accept a huge file upload.  CGI.pm will accept the upload and store it
7833 an uploaded file.  CGI.pm will delete the file automatically when it
7844 CGI.pm also has some simple built-in protections against denial of

7927 CGI.pm's ReadParse() routine creates a tied variable named %in,
7941 of CGI.pm without rewriting your old scripts from scratch.
7943 An even simpler way to mix cgi-lib calls with CGI.pm calls is to import both the
7951 =head2 Cgi-lib functions that are available in CGI.pm
