Often Web applications use sessions or server files to cache information between requests.

Using server files to cache application information works well for single server sites.

When you need to cache information to be made available to a site served by a cluster, using files is no longer an ideal solution, as it becomes much slower to distribute the information.

For sites that use server clusters, using memcache based solution to distribute cached information is much more efficient.

However, if the information to be distributed too large, a single memcache server may not be enough.

This class can cache information distributing it evenly among a cluster of memcache servers. It uses the cache item keys to compute an hash value to determine which of the memcache servers in the cluster is used.

Detailed description:

This class can be used to store and retrieve cached data from distributed cached servers.

It can connect to a memcache server from a list of servers to store and retrieve cached data.

The memcache server that it connects depends on identifier of the key use to access each cached data item. So, data items are cached in different servers to distribute the load.

The class can add, get, set, replace, delete, increment and decrement cached data items.

It can also invalidate all cached items in the whole list of memcache of servers.
