title: Redirect to previous page in zend framework
body: <p>I want to add a redirection URL to my login forms action (as a query) in login page, so after loging-in, one can visit the previous page he or she was surfing.</p>
  
  <p>First I thought about using Zend Session and save the url of each page in a variable. but I read in the documentation that it has overhead. So, is there a better way to do so? or is there an other way to use zend session with no overhead?</p>
