RAM Cache Settings:

Request Variables: 'AUTHENTICATED_USER', 'URL1' (each on their own line)

Threshold entries: 1000
Max. age: 3600
Cleanup interval: 300

The "URL1" is in there so that it gets cached on a per URL basis.  Is
that the right way to accomplish that?  It seems to work for everything

Doesn't seem to work is defined as four hits to the same page (URL) by
the same user gives the following in my statistics section:

Path: /<plone_instance>/getAllowedTypes
Hits: 0
Recent Hits: 0
Misses: 0 
Memory: 0
Entries: 0

Odd that it even mentions it?!? (with everything being zero)
