Sorry for being overly terse.

I meant the directory where PHP stores its session files. I think it's 
listed in the phpinfo() output for human consumption, and available via 
ini_get() for scripts.

You could create something like pub/<recipename>/cache.
(Makes installation a lot harder though. Sticking with the session 
directory is simpler.)


Whatever you do, make sure that you clean the cache from time to time.
A customer of mine had a script that generated graphics, and cached it 
in a directory. The cache was never cleared, so after two years, she hit 
the disk quota and didn't understand why so many of her scripts had 
stopped working (it wasn't initially obvious that it had hit just those 
scripts that tried to create another file).
