in thread POST vs GET & their intermingling.

Under no circumstances will the contents of the URL query string interfere with similarly-named CGI parameters in POSTed forms. If you try to mix a URL query string with a form submitted with the GET method, the results will not be what you expect.
I came to this same conclusion after reading the specification for the FORM tag.
