addHandler

Adds a handler to @server for requests prefixed by @path.

If @path is null or "/", then this will be the default handler for all requests that don't have a more specific handler. (Note though that if you want to handle requests to the special "" URI, you must explicitly register a handler for ""; the default handler will not be used for that case.)

For requests under @path (that have not already been assigned a status code by a class@AuthDomain, an early server handler, or a signal handler), @callback will be invoked after receiving the request body; the class@ServerMessage's method, request-headers, and request-body properties will be set.

After determining what to do with the request, the callback must at a minimum call method@ServerMessage.set_status on the message to set the response status code. Additionally, it may set response headers and/or fill in the response body.

If the callback cannot fully fill in the response before returning (eg, if it needs to wait for information from a database, or another network server), it should call method@ServerMessage.pause to tell @server to not send the response right away. When the response is ready, call method@ServerMessage.unpause to cause it to be sent.

To send the response body a bit at a time using "chunked" encoding, first call method@MessageHeaders.set_encoding to set %SOUP_ENCODING_CHUNKED on the response-headers. Then call method@MessageBody.append (or method@MessageBody.append_bytes)) to append each chunk as it becomes ready, and method@ServerMessage.unpause to make sure it's running. (The server will automatically pause the message if it is using chunked encoding but no more chunks are available.) When you are done, call method@MessageBody.complete to indicate that no more chunks are coming.
