session problem behind a firewall

[rwelte2003]

Hi,

I programmed some form pages, including a php session managment. All works fine, when I access these Pages from different machines at the same time (all of them with different IP Adresses ).
But it seems to be a big problem, when two (or more) people behind a firewall (all with the same IP adresses) trying to access the Pages at the same time.
I recognized, that in some cases the sessions were stolen undeliberate by another User, so the form could not be send correctly to the Database.

Could anyone help?

Thanks in advance, Randy

What strange, i think you are wrong check the webbrowser on the clientside. I cannot believe that two systems handle the same sessions...
