title: Is GAE Stateless? What are the implications?
body: <p>I was once told that GAE is stateless.  I understand the concept of statelessness in general but I could use some guidance in conceptually applying it to a GAE-type-system.</p>
  
  <p>I'm asking this question specifically because I an app I've developed appears to be having an interference problem.  That is, when two or more people use it at the same time, it becomes confused.  (I am continuing to bugtest to confirm that the error only occurs during simultaneous use.) I perceive that there are two ways such interference could theoretically occur: A, incorrect GQL queries getting the wrong db records(I checked this, nope); or b. at the server level.  My question: is the latter actually possible?  When the app is serving, can one user interfere with another by, say, changing the state of a variable within the program?  Or, perhaps, is this prevented by statelessness?  I am confused and may have misstated the question.  Namaste.</p>
