title: Application_Start in a web garden environment
body: <p>Running under IIS 7.5, I have a web garden. When IIS is restarted, does it only call <code>Application_Start</code> one time or is it one time for each web garden instance? I would like definitive proof.</p>
  
  <p>Also, as I understand it, each web garden instance is an exact clone. That means that if I add something to HttpContext.Cache in one instance it may not be available to HttpContext.Cache in another instance, is that correct?</p>
