I've got an asp page which calls an aspx page via MSXML2.XMLHTTP and processes the xml which is send back by the aspx page. The problem is that when the aspx page is called, always the same session is used. If two users call the asp page at the same time, the aspx page uses the same session for both users. This is probably because the MSXML2.XMLHTTP object does not support session cookies. Setting a cookie with .setRequestHeader "Cookie", "ASP.NET_SessionId=" & SessionID to link the session of the asp page to the aspx page does not work. The header is ignored by the aspx page, it just uses the same sessionid again. How do I force the aspx page to use a different session each time the aspx page is called?
Background: The aspx page creates an object which uses its own cache object the cache object is stored in the session object. Two or more requests to the aspx page are not allowed to share the same cache object. But they do now because the same session is used.
