Hi Friends, I am sure many must have come across this situation. I am developing an servlet based app where I add to a hash table a list of users who are presently logged in . The list can be easily maintained when the user initally logs in and decently logs out . But how shall i come to know that a particular users session has been timed out. Any suggestions or workarounds to this problem is welcome. Thanks
