Hi all

I m writing a web application which will work on multiple web servers for scalability and with load balancing .... like clustering ....

I m coding in PHP and AJAX ....

The problem is that if i have 2 servers in the cluster ,,, both working parallally in load balancing and if the server1 dies suddenly then according to the cluster function all the active sessions on the server1 will be shifted to server2 which does not have any idea of the active sessions on the server1 .... so all the sessions crashes and u have to create all new sessions ....

can anybody give me any enterprise level solution that all the active sessions on the server1 can be kept active when in case of failure they are shifted to server2 ....

any help on this will be appriciated ...
