I'm having a problem with Session variables.

I have several apps that are running under IIS. In my development environment I have a subdirectory under Inetpub in which I keep each project in a separate subdirectory.

In IIS I have created a vurtual directory for each app pointing to each subdirctory. At any time one app could call another. For some reason when one app calls another the session vars created in the
first app are lost.

However, if I remove all the virtual directories and only make one that points to the main development directory, then all works fine.

Is there something in the virtual directory schema that causes IIS to scope what appears to be a different session for each virtual directory app called?

Is there a way around this (other than what I have already done)???

Thanks,
Michael
