I have a perl app that works just fine on both Apache and IIS 6 on two different 32 bit Win 2003 Server platforms. However I have a problem with it on IIS 6 on Win 2003 Server x64. ActivePerl 5.8.9 build 826 and build 826 (64-bit) are installed. With CGI.pm I am creating web pages with the POST method to hide the posted variables.

For some reason on the x64 machine, after I click a submit button the second time, the passed variables from the prior submit action are now visible in the browser URL window with either IE7 or FF3.6 browsers.

For example, it would show:

http://mysite.com/pgm.pl?UserID=;Fcn=Login

With each successive Submit action, the prior list of vars is displayed. It is not clear what is going on, and why just on this server with x64 code. Any ideas on what I need to fix/check for?
