title: What can destroy a session object asp .net?
body: <p>I work with <code>Session[""]</code> objects in ASP .NET/C# MVC. I do a lot of checking on them,  but I ask myself, what can destroy a session object without I specify it ?</p>
  
  <p>I want to be sure that these <code>Session[""]</code> will be intact during some processes and can be only cleared by my instructions or if the user quit the application.</p>
