Whenever I have
'python manage.py runserver:8000'
going, and I try opening localhost(127.0.0.1:8000) in firefox, everything goes fine.
When I try to open localhost in IE9, IE9 chokes.
To prevent this, I use
python manage.py runserver 0.0.0.0:8000 and in IE9 I navigate to http://192.168.1.100:8000, the local IP of my pc.
In Pycharm this is possible by editing run/debug configuration, and fill in 'localhost' as 0.0.0.0
and runbrowser as http://192.168.1.100:8000/
I just wanted to share this trick.
