Tornado: Can I run code after calling self.finish() in an asynchronous RequestHandler?

Question

I\'m using Tornado. I have a bunch of asynchronous request handlers. Most of them do their work asynchronously, and then report the result of that work back to the user. But

Answer 1

Yes, your code after self.finish() will work reliably. But you can't call self.finish() twice - it will raise an exception. You can use self.finish() to close connection before all work on server is done.

But as Cole Maclean told - don't do heavy work after finish. Look for another way to do heavy tasks in background.
