I did just as you suggested with the following results:

1. With a direct connection, all variables are passed to the .cgi

2. Working through WinProxy, none of the variables are getting passed to the cgi from the form.

What is interesting is that with a direct connection, the HTTP_REFERER variable is form.html while through WinProxy, the HTTP_REFERER variable is the test.cgi? Yet both are being submitted from the same page.

Also, the HTTP_HOST ENV through WinProxy was the IP Address while with a direct connection it was coming through with the domain name.

So in the configuration of the cgi, I used a relative address for the cgi (../cgi-local/test.cgi) instead of the absolute http address, an now WinProxy is passing the variables. Not sure what is happening, but at least it now works.

Thanks for all the insight and suggestions.
