Run extension on page refresh?

Question

I am new to plugin/extension development in EE. I currently have an extension that creates a cookie and saves a value to it. What I want is on every page refresh this value to be updated.

Is there a way to have the extension run on each page refresh?

Answer 1

Yes: use the sessions_end hook. It runs on every page load. Be sure to check to see if you're using it on the front-end before you set your cookie (I assume you want this for the front-end only).

if(REQ != 'CP')
{
    // do your stuff
}
