I appreciate the help Rajesh,

I haven't added any special settings for the cachemiddleware, I just
placed 'django.middleware.cache.CacheMiddleware' in my middleware
classes and that's it. As far as the low-level caching that I have
written into my code using the "from django.core.cache import cache",
all of that is working fine. It's just the middleware that is the
issue. As soon as I set the cache middleware in my middleware classes
setting, that's when I start having problems.

Here is an example view, where I try to open a file and it gives me a
"ValueError: I/O operation on closed file":
view (the line it actually executes is line 24): http://dpaste.com/41671/
function it calls (open_system_file): http://dpaste.com/41672/

Every part of that view works fine except for when I go to open that
file on line 24. And it works fine in my tests.py, I get the exact
data that I am supposed to from the file (the specific test is on line
22): http://dpaste.com/41678/ (open_system_file on line 23 is defined
in system_methods on line 3)

And as far as stack traces go, I have my mod python error I just gave
you. Here is the apache2 error log (I blocked out my ip out of
paranoia): http://dpaste.com/41682/ I don't know what else to give you
that would help as far as problems within the stack. I'm not doing
anything db related, so if there is something else you need me to
post, please mention it by name specifically, in case there is
something I'm not thinking of.

Thanks for the help,
Brandon
