title: application_start event called multiple times in MVC application
body: <p>In my MVC application ,I am updating my web.config at runtime through application_start event.So, ideally it should be done only when the application is started.BUT in MY mvc application the application_start event of global.asax is being called multiple times , even when i have not restarted the application.</p>
  
  <p>Its being repetadly called when i am calling different actions , so the webconfig is repetedly updating &amp; making my application very very slow.</p>
  
  <p>Can you please let me know , what's the reason &amp; how to handle this .</p>
  
  <p>Thanks in advance
