Situation #1 would create a User object, populate it from Session variables
(which were populated from a single DB hit on Session_Start), and destroy a
User object on every Page_Load.

Situation #2 would create a User object for each Session only once, on
Session_Start, and save the User object in the Session object, which would
be destroyed when the Session timed out.

Either way, the DB is hit only once, which is the real performance
improvement. Now I just want to figure out which method is more scalable,
yet high performance? Creating a small User object on every Page_Load, or
stashing a User object inside Session?

A final question on this...if I were to go with method 2, storing the actual
User object in Session, I could simply call any methods of that object on
any page at any time, without instantiating the object, or worrying about
Disposing it, assuming its Dispose() method were called on Session_End?

Andy is right, web farm scalability may be another consideration. I'm
not sure if the Session server serializes objects when storing them - if
it does, both options will scale out just as well. If it only works
well for storing simple values, then #1 would be the choice for web
farms.

Without doing actual testing, anything anybody says will just be an
educated guess.

that said, my guess would be that #1 would be more scalable, while #2
would be more performant.

Yes, that's part of the beauty of that technique.

Wow, that is beautiful! Now I just need to find out from some of the MS
people if objects stored in Session on a dedicated Session server are
serialized...

If you use out of process session state, youl'l need to attribute your
class with [serializable]. Otherwise you'll get an exception when you
attempt to stuff the class into session.

Thx
