Tornado Web & Persistent Connections
- by Engrost
How can I write Http server in TornadoWeb that will support persistent Connections.
I mean will be able to receive many requests and answer to them without closing connection.
How does it actually work in async?
I just want to know how to write handler to handle persistent connection.
How actually would it work?
I have handler like that:
class MainHandler(RequestHandler):
count = 0
@asynchronous
def post(self):
#get header content type
content_type = self.request.headers.get('Content-Type')
if not content_type in ACCEPTED_CONTENT:
raise HTTPError(403, 'Incorrect content type')
text = self.request.body
self.count += 1
command = CommandObject(text, self.count, callback = self.async_callback(self.on_response))
command.execute()
def on_response(self, response):
if response.error: raise HTTPError(500)
body = response.body
self.write(body)
self.flush()
execute calls callback when finishes.
is my asumption right that with things that way post will be called many times
and for one connection count will increase with each httprequest from client?
but for each connection I will have separate count value?
