title: InProc vs StateServer
body: <p>We recently changed from using <code>InProc</code> to <code>StateServer</code> for storing Session information.</p>
  
  <p>I was wondering, if it's possible to update configuration files on the website now without losing session information. As when we used InProc and updated resource files (like language files), web config files, global.asax or files in the <code>App_Code</code>, we found that sessions appeared to reset and received errors like </p>
  
  <blockquote>
    <p>'Object reference not set to an instance of an object'</p>
  </blockquote>
  
  <p>Does this change with going to <code>StateServer</code>? Is it safe to update these types of files without losing the session data? I have run a couple of tests on our test system, and it appears that it works OK, but I'm not 100% confident...</p>
