jsf redirect


I read as

<redirect/> is an optional element which can be used to specify that the response is generated by the new view using redirect response rather than rendering the response as the current request. If we don't specify this element then the address bar shows the current page address even the response is generated by other page.

I have not understood what author meant. Why we have to use redirect within navigation-case of navigation rule within faces-config. Can you please advise. Any ideas, suggestions, links, resources, sample code highly appreciated. Thanks in advance

you use a redirect when you want the rendering handled by a different request
for example when handling a post you don't want the POST request to handle the rendering as a browser refresh would result in the post being sent again, potentially duplicating say an db update. So instead we redirect to a GET that just handles rendering the page
