Ok, thanks Jeff. I think I can work around that problem. What about this scenario: 1) Filter incoming request based on content (HTTP POST) 2) Stop further processing of a request if content matches (or doesn't match) dynamic criteria (Perl script is aware of these criteria) 3) do not pass request to mod_proxy_ but send 4xx response back to the client Is this doable with filters? If not is there any alternative solution? It has to be simple, I'm not considering writing a module for that purpose.
