Well I think I screwed up this post. This post is concerning the Cache headers. I added the code from the article and I am getting the following error. Not sure how to resolve this issue.

A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /Library/WebServer/Documents/system/application/libraries/MY_Output.php:2)

Filename: libraries/Session.php

Line Number: 662

Any help would be appreciated

And whats at line 2 in MY_Output? It sounds like you’re prematurely sending some whitespace to the browser
