Hey all,
I just made some modifications to sfProcessCache to use sfFileCache
as a default option if you do not have APC, XCache, or Eaccelerator
installed.
It is pretty simple, and the only assumption I make it the storage
path. I set the storage path to:
sfConfig::get('sf_cache_dir').DIRECTORY_SEPARATOR.'sfProcessCache';
I am not sold on this, due to the fact that you can not change it
without changing the class, or extending the class. This should be
refactored back into a YAML file, but I figure this may be useful now
to you all.
If anyone wants to get this into the symfony repository, feel free.
Also feel free to adjust anything (such as making the file path user
configurable).
Comments? Concerns?

I have only tested this with symfony 0.6.3. Your mileage my vary.
