Stores request/response pairs in memcached. Keys are not stored directly since memcached has a 250-byte limit on key names. Instead, the SHA1 hexdigest of the key is used.
cache | [R] | The MemCache object used to communicated with the memcached daemon. |
Create MemCache store for the given URI. The URI must specify a host and may specify a port, namespace, and options:
memcached://example.com:11211/namespace?opt1=val1&opt2=val2
Query parameter names and values are documented with the memcached library: tinyurl.com/4upqnd
