function ape_drupal_goto_alter in Advanced Page Expiration 7

Implements hook_drupal_goto_alter().

If a drupal_goto is called, detect if it is a 301 or 302 and set the cache-control header appropriately based on configured options.

This hook is used so we know the response code without having to use PHP 5.4.

File

./ape.module, line 69

Allows finer control of the Cache Control header.

Code

function ape_drupal_goto_alter(&$path, &$options, &$http_response_code) {
  $max_age = NULL;
  if ($http_response_code == 301) {
    $max_age = variable_get('ape_301_lifetime', 0);
  }
  elseif ($http_response_code == 302) {
    $max_age = variable_get('ape_302_lifetime', 0);
  }
  ape_cache_set($max_age);
  ape_set_cache_header($max_age);
}
