Running classic asp web application in recent DataFlex versions
From DataFlex Wiki
When trying to run a classic asp style web application in DataFlex 19.0 and newer you might bump into problems trying to run it.
This is because of the WebAppServerSession.PageScopedSession in the global.asa file.
When you create a new web application in DataFlex 19.0 then the Studio assumes you are trying to create a new style application and it will create a global.asa file where it assumes you do not need asp sessions any more.
For classic asp style applications this needs to be set to false.
WebAppServerSession.PageScopedSession=False
