Code

function httpbl_cron() {

  // Only continue when caching is enabled
  if (variable_get('httpbl_cache', HTTPBL_CACHE_OFF)) {
    if (variable_get('httpbl_cache', HTTPBL_CACHE_OFF) == HTTPBL_CACHE_DBDRUPAL) {

      // Also check status so that we do not accidentally delete the site's custom access rules.
      db_query("DELETE FROM {access} WHERE mask IN (SELECT hostname FROM {httpbl} WHERE status > 0 AND expire <= %d)", time());
    }
    db_query("DELETE FROM {httpbl} WHERE expire <= %d", time());
  }
}
