[FX.php List] No GC (Garbage Collection) in IIS installation

Sat Mar 20 13:08:10 MDT 2010

I asked my IT guy to adjust the permissions. He said he applied 
"Eveyyone/Full", so I assume that means 777.  We will now evaluate 
the need to dial that back.

And, I can't tell you if the trailing slash s needed, but it is there 
now.  I couldn't do too many iisrestarts during the day.

Will report back if I find that it is not needed.

What I can't figure out is why more folks haven't found this to a 
problem.  This is a by-the-books FMS  10 Server install with PHP API 
deployed.  It installs the php.ini with blank session path.

So why isn't anyone else screaming about 100,000's files stacking up?
