This software captures and displays HTTP traffic and it can also be used as a responder to simulate a server during load testing. HTTP Recorder is a software that allows you to capture and inspect HTTP traffic. For each session (request and corresponding response), it will display the headers, and 4 views of the body: Text, Hex, XML, and Image.
It can also be used as a responder to simulate an unavailable system during testing. In "Play" mode, if it receives a request that matches a request it has seen before, it will reply with the recorded request's response. When determining a match, it will consider "Headers and Body", "Headers Only", or "Verb and URI".

By default, HTTP Recorder runs as a proxy. Simply configure your client to use a proxy server. Alternatively, HTTP Recorder can run as a gateway. A gateway is an intermediary between a client and server. Provide the destination endpoint (Host and Port) to HTTP Recorder and change the clients reference to the destination endpoint with HTTP Recorders endpoint.
