APC cache implementation.

Code

function __construct($bin) {
  $this->bin = $bin;
  $this->drush = drupal_is_cli() && function_exists('drush_log');

  // First we determine the prefix from a setting.
  $prefix = self::getPrefixSettingForBin($this->bin);

  // If we do not have a configured prefix we use the HTTP_HOST.
  if (empty($prefix) && isset($_SERVER['HTTP_HOST'])) {

    // Provide a fallback for multisite. This is on purpose not inside the
    // getPrefixForBin() function in order to decouple the unified prefix
    // variable logic and custom module related security logic, that is not
    // necessary for all backends.
    $prefix = $_SERVER['HTTP_HOST'] . '::';
  }
  else {
    $prefix = $prefix . '::';

  // When we are in testing mode we add the test prefix.
