[web-devel] Potential gotcha in setSession/setCreds functions in

Maybe this is obvious to others, but it wasn't to me. Any code that sets a cookie or session variable wont "take effect" until the next request. Upon reflection, this should have been obvious to me because the session vars are read out of a Reader monad, but it wasnt..
My point is that, you can't do something like:
setCreds False creds
m <- requireAuthId
in a single request. The simple solution is to stick a redirect in there. Not suggesting any code changes, but a simple note in the haddocks :)
Again, sry to bother if this should have been obvious too me.
