JSF page redirect rule

As you can see in the previous examples urls are not changed while navigating from one view page to another because JSF by default uses forward functionality instead of redirect. For page redirection we have to append faces-redirect=true at the end of the view name.

Syntax:

pageName?faces-redirect=true

Example explanation:

When “Welcome” link is clicked welcome.xhtml page will display. But the thing to be noticed here is the change of url because of the redirect navigation rule.

Example:

test.xhtml

<?xml version="1.0" encoding="UTF-8"?>
