@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.
