title: How to pass data when redirecting from one web application to another?
body: <p>I have two web application which are deployed in the same J2EE Application server. I need to redirect from one web application to another. Also I need to set some information in the Header from web application 1 so that it is available in web application 2. 
  When I try to access the information which set in the header of Web App1 in Web App2, I'm getting  "null". I'm using <code>response.sendRedirect("http://localhost/webapp2")</code> in Web Application 1 to redirect. Please help me to solve this.</p>
  
  <p>Thanks,
  Apps.</p>
