Regarding the Set_cookie() function and cookie behaviour.

if you specify a path, the cookie vars are only available 
in those directories! And strange enough partial path 
strings DO match:
cookie in "/test" is also available in "/test2" and 
"/testbed". But cookies set in "/testbed" are not available 
in "/test" etc. i.e. a partial path string DOES match !! 
(not good)

Furthermore, i see in explorer(mac) that for all subdirs a 
'accept cookies for www.domain.com' is set.

This IS a problem if you work on several projects in 
subdirs that use the same cookie var names, for instance 
used in a common AUTH-LIB. And if you use different var 
names, you can only work on 20 projects (max cookies per 
domain)
