depending on what you want to do, some things are possible. If you want to parse an HTTP request, it is possible since 1.4 and you can use that result to select a backend (server group). But in order to be able to parse an HTTP request in TCP mode, you need first to match the req_proto_http, which will ensure you have the complete request buffered. Regards, Willy
