What you are trying to do does not make a lot of sense with HTTP semantics. Still, I'll try to help you with your coding issue. 1) Work on squid 2.5 or 3.0 . Squid 3.0 is in C++ which should be easier for your Java background. Certainly 2.3 is old an it's unlikely folk will take the time to look up what you are doing. 2) in C and C++ the address of structs in memory matters a lot when pass by reference is used. Thus mem copying from one location to another will not achieve your goals - you will lose refcount accuracy, and will end up with dangling pointers. What you need to do is duplicate the entire composite structure - clientHttpRequest, fwdState, store_client, MemObjects etc that make up a request. A better approach would be to start a new internal request to get the object, and then just send an error to the original one, similar to what fwdFail does. Rgarding the client fd == -1 thing, a client fd of -1 indicates that there is no client waiting for data, or that it is an internal request.
