I’m trying to use a class level variable @@count as a counter between  
requests to the server. So for example I initialize it @@count = 0 at  
the top of the class and in a method I have @@count = @@count+1. It  
seems though that @@count is begin reinitialized back to 0 each time the  
controller is called. Is there something that I’m missing here? I’m  
running under mongrel on Linux.

Well for every request to the server you would get a new class variable  
🙂
