hi monks
i have a problem.
i wrote a program for image upload and it only allows to restricted user
for that i create a cookie on the basis of userid when user logon and it expiry time is set to 30 min
but within the 30 minute if other user login i overwrite
the cookie with the new userid but at the time of fetching
the userid from the cookie it gives me the old userid for the first time
and when refresh the same page then it is giving the correct userid i think it is cache problem can anybody help me out of it,
thanx in advance
