To my knowledge, routers don't generally route based on session. They 
maintain flow information is cases, but you learn quickly that it's a 
one way record, and the corresponding flows may have a different path.

There are exceptions, and perhaps some Junipers even support more 
oddball session based routing, though my m120 and cisco don't seem to.
