title: Access session in class library.
body: <p>I am developing an application architecture that uses 2 sub projects: 
     a) asp.net web application (it covers user interface and business logic)  and 
     b) class library.    (it covers data access layer)</p>
  
  <p>After system user successfully logs in , the user information is stored in a session object.</p>
  
  <p>The problem I am facing is when I try to access that session object in class library project(data access layer), it always returns null.</p>
  
  <p>I need to access the session object in class library project because, in my case each user has their own username and password for database access(for security reasons);</p>
  
  <p>So, How how do i read and write from/to session object in class library project</p>
