Subject: Re: [users@httpd] Re: mod_rewrite Scenario Assistance

Sorry, by CGI variables, I meant the webserver variables.  Stored in
the CGI scope by ColdFusion and in the SERVER[] scope in PHP, if that
helps.  Variables like SCRIPT_NAME, HTTP_REFERER, etc.

I tried your sample code against several use cases and it does
everything our current module does and more.  I still have to test the
webserver variables to know whether I have to pass the URL in the
query string, but I think that should be a formality.

Thanks again for all of your help.  Without it, this effort would have
taken significantly longer than it did.  I appreciate that.
