async http request on Google App Engine Python

Does anybody know how to make http request from Google 开发者_开发问答App Engine without waiting a response? It should be like a push data with http without latency for response.

I think that this section of the AppEngine docs is what you are looking for.

Use the taskqueue. If you're just pushing data, there's no sense in waiting for the response.

What you could do is in the request handler enqueue a task with whatever data was received (using the deferred library). As soon as the task has been enqueued successfully you can return a '200 OK' response and be ready for the next push.

I've done this before by setting doing a URLFetch and setting a very low value for the deadline parameter. I put 0.1 as my value, so 100ms. You need to wrap the URLFetch in a try/catch also since the request will timeout.
