Sorry for the late reply. I've been a little busy in the last two days.
You are right, dynamic includes is not used for sesion variables and filtering recordsets.
There's another thread "Replacement for ADDT Dynamic Lists" showthread.php?t=4268
I just mixed both topics. Sorry for causing any confusion.
Anyway, "Server-Side Includes" and "Server-Side Includes from List" are (at least for me) the most important features, I used.
