Description
For almost every request made by IE9 beta the development server hangs or results in the following stacktrace:
---------------------------------------- Exception happened during processing of request from ('127.0.0.1', 51855) Traceback (most recent call last): File "C:\Python26\lib\SocketServer.py", line 283, in _handle_request_noblock self.process_request(request, client_address) File "C:\Python26\lib\SocketServer.py", line 309, in process_request self.finish_request(request, client_address) File "C:\Python26\lib\SocketServer.py", line 322, in finish_request self.RequestHandlerClass(request, client_address, self) File "d:\django-sites\django-trunk\django\core\servers\basehttp.py", line 569, in __init__ BaseHTTPRequestHandler.__init__(self, *args, **kwargs) File "C:\Python26\lib\SocketServer.py", line 617, in __init__ self.handle() File "d:\django-sites\django-trunk\django\core\servers\basehttp.py", line 609, in handle self.raw_requestline = self.rfile.readline() File "C:\Python26\lib\socket.py", line 444, in readline data = self._sock.recv(self._rbufsize) error: [Errno 10054] An existing connection was forcibly closed by the remote host ----------------------------------------
To reproduce this, for me it's enough to start a new project with django-admin, run the development server and try to load an URL. Sometimes it takes one or two refreshes of the page to get the exception. After the exception appears the development server is completely hung, it won't respond to requests from other browsers until it's restarted. This makes the development server totally unusable in combination with IE9 beta.
This thread suggests that other people experience this as well.
Software versions that I used:
- Django SVN HEAD from today (revision 15343)
- IE9 beta
- Python 2.6.6 32 bit
- Windows 7 64 bit

I'm experiencing the same issue.
Django 1.1.2, Python 2.6, Windows 7 64bit, IE9 beta.
Can be reproduced immediately by using Ctrl+F5 for refresh.
I am not going to reopen as I guess it might have nothing to do with Django in particular.

Would you be so kind and disable the Windows (or any other) firewall software for a moment and try again?

I tried disabling the Windows firewall and the problem persists. I also upgraded to IE9 RC and it still happens. NOD32 is running on the machine with problems and has some web access protection feature that might interfere but disabling that doesn't help either.
However, on 2 other PCs running Vista and IE9 I'm not seeing the problem. They didn't have NOD32, I added it on one but it still works. So far the only obvious difference between the 2 machines where I saw it working and the 2 where it doesn't is Vista vs. Windows 7. Jezdez, which one of the two did you test?

I've run into this issues in earlier django versions with certain browsers. One solution I found is to avoid using any aliases like http://localhost:8000/ and instead use http://127.0.0.1:8000/

I also had the problem with IE9, I foudnt hat by using the real IP address of the machine when starting the dev server instead of the default seemed to resolve the issue. Not sure why or whats really going there but this issue is popping up more and more doing some google searches.

If anyone who has this problem is can provide a wireshark dump of the traffic while this issue is being seen, it might help the rest of us replicate/debug it.
I'd be willing to bet that this issue (at least some incarnations of it) may be due to the single-threaded nature of the dev server in the current stable versions of Django. If a IE has opened a request, it may not be properly closing it, or may leave it open in the background to finish downloading something when the page is refreshed, leaving the one server thread hanging, never to complete.
The new multithreaded dev client may fix this issue.

Indeed, I can confirm that changeset 16427 (which makes the development server multithreaded) fixes the bug for me. Going back to changeset 16426 makes it fail again. Sorry for trying it out so late after PaulM's suggestion.
Jezdez hasn't been able to reproduce this; the mailing list thread seems to suggest that the problem may lie with network settings on the box in question.
If you can narrow down *specific* test conditions that reproduce, feel free to reopen with details.
