This is similar to a previous project, but this project has a key variation: I'd like to share session information between ASP Classic => PHP using neither a cookie or a database.
Simply put, the objective of this project is to pass a session variable from ASP to PHP using shared memory. A creative approach may be required, but this passage, copied from a similar problem posted on Stack Overflow ([url removed, login to view]), may be very helpful as a starting point.
If you can come up with a creative approach that meets this criteria, we can discuss. If you need further clarification, we can also discuss.
