Has ASPexplore 100% compatibility with the latest Internet Information Server?
No and it will never have. Until now ASPexplore has implemented 4 built-in Active Server Pages objects (Server, Session, Request, Response). We have been trying to implement these objects as close to the IIS versions as possible but they have some limitations and occasionally they behave in a different way than you would expect. The work on ASPexplore Software and introduction of new features is still going on.
