I have discovered a very strange thing. First I thought it was only me and I posted the problem on phpbuilder.com, but then it seemed that many other people are having the same problem.

The problem is that session management in php4 on a windows machine fails to work when using the php4isapi.dll. 
Till the last beta the session management worked without any problems, but from the rc1, so also the rc2 and the final release session management just refuses to work. As soon as the browser requests a file with a session_start or session_register command the browser gets in a kinda endless loop. The browser keeps waiting and waiting and nothing happens (nothing appears on the screen).
If I change php4isapi.dll into php.exe in my iis settings it works, but that will decrease the performance, right.

As I said, until the last beta it worked fine, but from the first release candidate it didn't work anymore.

And since many people are having this same problem I guess it's a major bug, right.

With regards

Frank
