在长时间运行的AJAX调用中离开页面时，防止Django异常

Question

In my application, I fire off an Ajax get request using Jquery on page load. If the call takes an unusually long time, the user may navigate away from the initial page during their standard browsing session. Eventually, this ajax call completes and fires a response back. The problem is, by this time the user has left the page and nothing is listening for a response any more. I get this exception in my logs when that occurs.

----------------------------------------
Exception happened during processing of request from ('98.x.x.x', 36495)
Traceback (most recent call last):
  File "M:\Python2.7\App\lib\SocketServer.py", line 582, in process_request_thread
    self.finish_request(request, client_address)
  File "M:\Python2.7\App\lib\SocketServer.py", line 323, in finish_request
    self.RequestHandlerClass(request, client_address, self)
  File "M:\Python2.7\App\lib\site-packages\django\core\servers\basehttp.py", line 139, in __init__
    super(WSGIRequestHandler, self).__init__(*args, **kwargs)
  File "M:\Python2.7\App\lib\SocketServer.py", line 640, in __init__
    self.finish()
  File "M:\Python2.7\App\lib\SocketServer.py", line 693, in finish
    self.wfile.flush()
  File "M:\Python2.7\App\lib\socket.py", line 303, in flush
    self._sock.sendall(view[write_offset:write_offset+buffer_size])
error: [Errno 10053] An established connection was aborted by the software in your host machine
----------------------------------------

How can I prevent this from happening?

None of the files listed in the exception are my code.

这个问题与在请求新页面且答案相同时如何在Django中取消ajax请求的功能相同。

Answer 2

This will only happen when you use the django development server, which tries to log exceptions on the console.

However, with other webserver (like apache) you will get similar exception but probably not so much descriptive.
