[imp] IMP 3.2 setup always using URL sessions

[Michael Bull]

I've had a look at the list archives and dig some hunting around myself, 
but can't figure out why the test IMP 3.2 setup I'm configuring is 
insisting on using URL based sessions.  I've tried several browsers all 
accepting cookies and working fine with our IMP 3.1 setup... but no dice, 
all use URL sessions.

It *is* is a different version of Apache/PHP, though - I'm using PHP 4.2.3 
(the latest of the 4.2s, if I have the version wrong).   Any ideas what I 
should double check?  I have a feeling I'll kick myself when I find it, but 
I'll take any bone people can throw me. :)   Thanks!
