You need to lock the read in case of another page updating it, particularly
in the case of frames.  You are correct, logically it should never happen,
but a "better safe than sorry" approach in CF code design.

okay, pete, thanks, i can dig that

it still does not explain why i have to *lock* the read of the session
variable

wouldn't all reads get the same value?

obviously i am super dense today
