Provides class for memcached data handling.

Class

MemcacheStorage

Class handles memcached cache objects.

Code

  // Such cached data invalidates during cache_get() operations.
  if ($expire == CACHE_TEMPORARY) {

    // We should set expiration to 0 for temporary cache.
    // This type of cache could be expired after fetching from memcached storage.
    // @see MemcacheStorage::validateItem().
