HTTP cache control headers

I had to do two things today. One was to make sure that in production all of my resources were cached. The other was to make sure that in development none of my resources were cached. I ended up with these two functions, which seem to be doing the trick to disable/enable caching:

function set_nocache() {
  header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
  header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
  header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
  header("Cache-Control: post-check=0, pre-check=0", false);
  header("Pragma: no-cache");
}

function set_cache() {
  header('Expires: ' . gmdate( 'D, d M Y H:i:s', time()+31536000 ) . ' GMT');
  header('Cache-Control: max-age=31536000');
}

Reference: Completely disable any browser caching.

Adding an app/page to a Facebook Page

I found this article which said to add a page/app to a Facebook Page you need to hit this URL with your two parameters:


https://www.facebook.com/dialog/pagetab?app_id=YOUR_APP_ID &display=popup&next=YOUR_URL

Update: I was trying to add an ‘app’ rather than a ‘page tab’ and it turned out I needed this:
