Django caching issue
Question: When I'm changing something in .py files, the changes are not shown
immediately, but after few minutes (even half hour). I'm restarting, reloading
apache, this don't help.  
I'm using Apache2 with mod_wsgi on ubuntu server.

It doesn't even create .pyc files.

Here's my [settings.py](http://pastebin.com/1DVhHUhA) file. What can I do to
disable caching?

Answer: Make sure you read:

  * <http://code.google.com/p/modwsgi/wiki/ReloadingSourceCode>

It details what you need to do to ensure a proper restart and have code be
reloaded. What is required depends on what mode of mod_wsgi you are using.
