hi Bibeault
actually i want to intercept the incoming Http request packet.My goal is to implement reverseHTTP ,so when ever i get a http request on tomcat form client (call it xyz web server which is customized to make http request) i want to read its header and if in its header something like "PTTH" (reverseHTTP) is found then tomcat will generates a http request to the client (xyz web server)...thanks for reply

Can't you just use a Filter?

Actually, sounds like a Valve, if it's not application-specific. But I've got to admit that messing around with protocol structures sounds like an over-complicated solution. If the client knows enough about this customized Tomcat to formulate a callback request, it should also be capable for sending normal app requests to do the same thing.

Customer surveys are for companies who didn't pay proper attention to begin with.

Ya tim correct but in general scenario server always give http respose to client not http request ....not all way server will expose underlying socket , so that instead of sending a respose message server let you send a request message to the client ,,,read this
