/**
@class Http::HttpRequestHandler
HttpRequestHandlers are attached to the HttpServer and process
incoming HTTP requests. When an Http request comes in, the
HttpServer asks every attached HttpRequestHandler until the first one
accepts the request. If the HttpRequestHandler accepts the request
its HandleRequest() method will be called with a pointer to a content
stream. The request handler is expected to write the response to the
content stream (IMPORTANT: don't forget to set the MediaType on the stream!)
and return with a HttpStatus code.
