title: How to pass url parameters without showing them to the end user in Salesforce?
body: <p>I want to pass a url parameter in salesforce, but it shouldn't be visible to the end user in the url. Is it possible? Please suggest if there are any other alternatives? Thanks in advance.</p>
  
  <p>In my scenario, I am dealing with 2 pages with individual controllers. In one of the page I am dealing with apex tabs. So I want to get the current tab name. I found the solution for this as passing it into to the url.</p>
