deepak_biswas19,

Based on your question I am not exactly sure what your looking to do. Have you had a look on the Cpan for the Apache::Session module? It may be what your looking for.

Update: I notice your previous node 'Shared memory' that this advice was already given. Are you having problems with implementing this? If so you should have posted a follow up node to your first question rather than ask again. Please read the PerlMonks FAQ if you have not already done so.

Hope this helps.

Martin
