If both ISA and Squid are having the same thing happen it sounds like a problem with the Client-Side code of the Site to me,...could also be a problem with the Server-Side Code trying tro improperly retreive the data..  In anycase, it seems like a Code problem with the Site itself.

Since it is a get request, you can try to mimick the squid and ISA servers by issuing a get request directly to the apache server from the browser.  If you can see in the access logs a sample request, put that in your browser and execute it to validate whether the client is not sending the data or the server is stripping it away.
for example:  http://my.server.com/someForm.php?var1=value1&var2=value2 etc...
Check the Apache access logs and confirm that the full URL as requested from the browser shows up in the logs.  While this won't isolate the problem totally, it can help you determine if the issue is in the server configuration, the server code or the client side code sending the data.
You could also use a client side tool like firebug in Firefox or Fiddler in IE to see what get requests are being issued from the browser to confirm that the client is sending the requested data.
At this point, like pwindell above suggested, you probably need to isolate if the issue is happening when the user hits submit in the browser, when the request get proxied, when the apache server processes the request or when the application code gets the data.

Solved, the problem was in my apache conf that we do a rewrite including the http_ip_fordward header value without escape.
Thanks to all
