does aspx provide special treatment for c# static variables
===

in a .net web app is there something special about .aspx pages and the c# code behind pages that changes the behaviour of static variables.

i have a large number of application pages that were developed elsewhere and there is a common pattern running thru them where what i think should be an instance variable is declared as a static variable.

a more detailed statement of the question would be:  if i have two web sessions a and b running on the same iis server in the same application pool, if a accesses the page in question and sets static variable x to value1 and then b accesses the same page and sets static variable x to value 2, my understanding is that value1 has been replaced by value 2.  my dilemma is that this pattern is used repeatedly in the code, at a high level the code appears to work.  the conclusion is that it is either luck (timing as in session a has abandoned the need for the variable before session b hits it) or there is something else going on.

i am open to suggestions whether this is a c# nuance or a developer bug.
