I have 2 sites that are on different servers and domains but I would like to pass from one to the other with out having to re-authenticate.
Both sites use the same DB so my thought was have an Auth Table where I place a GUID, the users ID, and a time stamp. I would pass the GUID in the URL and do a lookup to see if the GUID is in the table and is less then X old, if so authenticated the user.
Any thoughts?
