Erm, it should do. Proxy caches shouldn't be caching any returns from
CGI scripts as these are likely to be dynamic documents (ie they can
change between invocations). If the CGI script is called and then
returns some arbitrary HTML document, that document is the one that the
browser should display.

And it can also spit out the empty form (or whatever it was you wanted to
reload) once the form has been processed. That was what was originally
asked for I thought.

Maybe there are some really broken caches that cache the output of CGI
scripts that I wasn't aware of though...
