Communicate from HTTPModule to php application

Hello, 

is there any possibilty to send information from an HTTPModule to a PHP application hosted in II7?

without using a file as intermediate.

I managed to  add or edit  values to the HttpRequest.ServerVariables collection in the HTTPModule I've created (e.g. OnBeginRequest)  

but this is not seen from PHP ($_SERVER, $_REQUEST).

Thank you in advance,
