/**
* Store data at the server
*
* CacheRedis::put() stores an item $buff with $key on the Redis server.
* Parameter $valid_time is expiration time in seconds. If it's 0, the item never expires
* (but Redis server doesn't guarantee this item to be stored all the time, it could be delete from the cache to make place for other items).
*
* Remember that resource variables (i.e. file and connection descriptors) cannot be stored in the cache,
* because they can not be adequately represented in serialized state.
*
* @param string $key The key that will be associated with the item.
* @param mixed $buff The variable to store. Strings and integers are stored as is, other types are stored serialized.
* @param int $valid_time Expiration time of the item.
* You can also use Unix timestamp or a number of seconds starting from current time, but in the latter case the number of seconds may not exceed 2592000 (30 days).
* If it's equal to zero, use the default valid time CacheRedis::valid_time.
* @return bool Returns true on success or false on failure.
