title: How can I use Session Variables to output login username
body: <p>I'm building an application and have just added a Login page which works well, communicating with a "username" and "password" field in the database. After logging in, it takes you a page users are authorized to see.</p>
  
  <p>Is there a way I can display "Welcome, xxx" to the particular user logged in at the next page? And more importantly, output detailed information of the logged in user on that next page? Thanks.</p>
