title: PHP session sending header "Cache-Control: no-store, no-cache, must-revalidate". How to change to "Cache-Control: s-maxage=10, public, max-age=10"
body: <p>PHP session is causing each page to contain the header <code>cache-control: no-store, no-cache, must-revalidate</code>.</p>
  <p>I need to override this behavior and change it to <code>Cache-Control: s-maxage=10, public, max-age=10</code> or even just <code>cache-control: public, max-age=10</code>.</p>
  <p>I've tried to use session variables <code>session_cache_limiter('public');</code> and <code>session_cache_expire(1);</code> but, the expire value is in minutes and I cant work out how to set it to 10 seconds.</p>
  <p>How can I set <code>session_cache_expire(1);</code> to 10 seconds?
  If that's not possible, how else can I override the session header and set the cache control to 10 seconds?</p>
