Django: IE doesn't load localhost or loads very SLOWLY
It might be related to this issue: https://code.djangoproject.com/ticket/16099
Essentially, the dev server isn't multithreaded, and if the browser opens a connection and then tries a second connection to actually get the data, it can hang forever.
Edit:
Also, see this issue: https://code.djangoproject.com/ticket/15178
If you can provide a way to reproduce the issue, we may be able to find a fix.
Also, if you could try the latest development version and see if that fixes it, we recently committed a new patch that adds multithreading capability to the runserver command.
