Page Cache disables redirect

[OriyanJ]

I've created a system plugin (using onBeforeRender and Mobile_Detect) to redirect mobile users to my mobile sub-domain, but it seems that when System - Page Cache is enabled, that redirect doesn't work. I believe it has something to do with the ETag.

I'm using a simple code to do that:

Code: Select all

$detect = new Mobile_Detect();
if ($detect->isMobile())
    header('Location: '.$url);

What could be the cause of this matter?

Well, I found out what I was doing wrong. Instead of using the onBeforeRender I should have used the onAfterInitialise.
