weird x-forward-for problem

using egroupware i have the problem with its sessions handling.

On certain key pages the x-forward-for details are getting lost, so
egroupware sessions stops it from happening

But this only happens with some browsers
firefox - i happens all the time
konquerer - it happens alot
IE 7 - it has not happened yet
safari - it has not happened yet

Any idea why some browser would run into this problem and others do not?
