From the developer:
WebBug lets you enter a URL, then displays exactly what it sends to the Web Server and, when the response is received, exactly what the Web Server sends back.
This is a `fun` program if you`re curious about the HTTP protocol, and is a useful `debugging` tool if you are trying to resolve a problem.
