Redirect via cookie. Should I include header.php as non-cached?

Hi guys,

In header.php I’m using some code to redirect people to some pages according to their browser’s language of choice.

Something like: “if your browser is in english, please go to A, if it’s in french, please go to B”

At the same time, this code runs only once, thanks to a session_start(); (cookie), that makes it work only if it’s the first time they hit the homepage.

How will W3 Total Cache manage that when page-caching the home if I have that code?

Is it advisable to include my header.php (with redirect + cookie) in the “exclude from caching” box?

Many thanks for your help,
