Call a function/run code on every page that is visited

I will start using Cloudflare soon and because all IPs are the same for every visitor i need to rewrite these to the real ones given in a special HTTP header by cloudflare. To make the IPs visible to dolphin system wide i need to run this code on every page that is called

if ($_SERVER["HTTP_CF_CONNECTING_IP"]) {
       $_SERVER["REMOTE_ADDR"] = $_SERVER["HTTP_CF_CONNECTING_IP"];
}

Where is the correct place to put such a code? Anybody knows?

Not entirely certain on this one, but I'd start with the _header.html file from within your current template directory. 

This will present the code on every page of your Dolphin site.

well...   you cant run php inside an html file...   so maybe  /inc/header.inc.php would be a better place to start.

in design.inc.php line 124

PageCode function.

Good luck

PageCode() -> Perfect, this is what i was looking for :)

Thanks

 you're welcome :)
