v2.2.1 - Show latest stable - Class: CGI::Session::MemCacheStore

new(session, options = {})

public

Create a new CGI::Session::MemCache instance

This constructor is used internally by CGI::Session. The user does not generally need to call it directly.

session is the session for which this instance is being created. The session id must only contain alphanumeric characters; automatically generated session ids observe this requirement.

options is a hash of options for the initializer. The following options are recognized:

cache:

an instance of a MemCache client to use as the

     session cache.

expires:

an expiry time value to use for session entries in

    the session cache. +expires+ is interpreted in seconds
    relative to the current time if its less than 60*60*24*30
    (30 days), or as an absolute Unix time (e.g., Time#to_i) if
    greater. If +expires+ is +0+, or not passed on +options+,
    the entry will never expire.

This session’s memcache entry will be created if it does not exist, or retrieved if it does.
