more about isapi functions

More that I don't quite understand: not only does a function persist between calls to a specific frame, but it seems that it persists between different pages in a frame. file A is called into frame 1. file B is then called into the same frame 1, replacing file A. any functions in file A seem to be available to the subsequent file B. Is that the way it should be? I guess I'll have to put all my php functions in the parent page. Has anyone put together an authentication script using PHP4 sessions rather than the base library? -------------------------------------------------- Avrum Goodblatt goodblat@sprynet.com (415) 9451368 http://home.sprynet.com/~goodblat
