Best way to avoid chunked encoding in HTTP Resource response?
by Tom Sheffler April 19, 2012

April 19, 2012

A straightforward use of a series of request.write()s with a request.finish() in the render_GET() method of a resource defaults to chunked encoding. I can avoid the chunked encoding by computing the entire response first using a StringIO (as shown below) and explicitly putting the "Content-Length" header in myself. Is this the best (or recommended) way to create such a response? Thx - Tom ============= class myresource(Resource): def render_GET(self, response): output = StringIO.StringIO() output.write("...") output.write("...") ... data = output.getvalue() output.close() # Write the response data. "content-length" suppresses chunked coding request.setHeader('content-length', len(data)) request.write(data) request.finish() return True

Is there a good way to mount both an HTTP Site and a WebSocket Server on port 80?
by Tom Sheffler April 9, 2012

April 9, 2012

I was wondering about ways to mount different types of protocol handlers on the same port. It looks like there will be new WebSocket support implementing a websocket Site. We'll also have the existing HTTP Site. Will they both be able to live on port 80? Is it important to be able to do this? In my own experiments, I've modified "portforward.py" to inspect an incoming request and dispatch to one of two different servers mounted on Unix-Domain sockets, depending on the request path in the header. It looks something like the code below. This does a lot of copying of each data packet, but seems to be effective. Does anyone have a better suggestion for how to mount different protocol handlers on the same port? Thanks. -T ======== site1 = twisted.web.server.Site(...) site2 = txws.WebSocketFactory(...) reactor.listenUNIX("site1.sck", site1) reactor.listenUNIX("site2.sck", site2) # this routes requests on port 80 to one of the two sockets reactor.listenTCP(80, InspectingProxyFactory("site1.sck", "site2.sck") =======
