Rick Strahl's book talks about this. I think you need a syntax like:
oSess.Item("VarName") for it work in VFP. VBScript syntax does some defaulting that isn't allowed in the VFP domain.

>>>I create a new session var.
>>>Session("side") = "test"
>>>in global.asa file. How would I pull that var. in VFP?
>>>Thanks Mark

>>You can send it as a parameter through a call to a com object...
>Yes, I do send a Session object to VFP COM.
