weini has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

I am not programming very often, so sorry for a dumb question ...

Using CGI.pm I create a form with the functions start_form() and end_form() - no problem here. The default parameters are allright for me.

My problem is that running the script on one webserver I get the right action="/~myname/cgi-bin/myscript.pl" while on another server it's changed to action="%2Fcgi-bin%2Fmyscript.pl" which causes an error in executing.

How can I make sure that the slashes are NOT converted to "%2F"?

Any clues? Thank you!

    CGI.pm's html generation functions are famous for this kind of thing. On a side node, I vaguely recall that apache, or some versions of it, do seem to interpret %2F as a / before a ?, so /a%2Fb/ is interpreted as /a/b/.

    I'm not sure what the RFCs say, so I suggest you find out what it's supposed to be, and then figure out if that's the wrong behaviour on behalf of CGI.pm.

      CGI.pm 2.99 is absolutely broken, thanks to a rushed patch to fix a cross-site scripting problem. 3.00 is fixed again, thanks to my corrected patch.

      Do not use CGI.pm 2.99 (it's broken), or any version prior to 2.99 (it has a cross-site scripting hole).

      Yep, that's it, thank you very much! I've downgraded the CGI and it works fine.
