self.new(*args) — MemCache — Ruby on Rails 2.3.18

self.new(*args)

Accepts a list of servers and a list of opts. servers may be omitted. See servers= for acceptable server list arguments.

Valid options for opts are:

[:namespace]   Prepends this value to all keys added or retrieved.
[:readonly]    Raises an exception on cache writes when true.
[:multithread] Wraps cache access in a Mutex for thread safety. Defaults to true.
[:failover]    Should the client try to failover to another server if the
               first server is down?  Defaults to true.
[:timeout]     Time to use as the socket read timeout.  Defaults to 0.5 sec,
               set to nil to disable timeouts (this is a major performance penalty in Ruby 1.8,
               "gem install SystemTimer' to remove most of the penalty).
[:logger]      Logger to use for info/debug output, defaults to nil
[:no_reply]    Don't bother looking for a reply for write operations (i.e. they
               become 'fire and forget'), memcached 1.2.5 and later only, speeds up
               set/add/delete/incr/decr significantly.

Other options are ignored.
