// This header file defines a dummy HTTP server that listens on a port for a connection, which
// when connected is serviced by validating the request data and sending a canned response.  The request and
// response data is obtained from text files specified in the URL:
//
// e.g. http://127.0.0.1:8000/?req=request.txt&resp=response.txt
