NAME

       Jifty::CAS::Store::Memcached - A memcached backend for Jifty's Content-Addressable Storage facility

SYNOPSIS

       At the bare minimum, add the following to your Jifty config.yml:

	   framework:
	     CAS:
	       BaseClass: 'Jifty::CAS::Store::Memcached'

       The options available include:

	   framework:
	     CAS:
	       BaseClass: 'Jifty::CAS::Store::Memcached'
	       Memcached:
		 # any options Cache::Memcached supports
		 servers:
		   - 10.0.0.2:11211
		   - 10.0.0.3:11211
		 compress_threshold: 5120

	       # Turned on by default. Keeps CAS working when memcached fails by
	       # falling back to the default in-process store. It probably should
	       # be turned off in most cases (like so) after successful testing.
	       MemcachedFallback: 0

DESCRIPTION

       This is a memcached backend for Jifty::CAS.  For more information about Jifty's CAS, see "DESCRIPTION" in Jifty::CAS.

METHODS

   memcached
       Returns the Cache::Memcached object for this class.

   _store DOMAIN NAME BLOB
       Stores the BLOB (a Jifty::CAS::Blob) in memcached.  Returns the key on success or undef on failure.

   key DOMAIN NAME
       Returns the most recent key for the given pair of "DOMAIN" and "NAME", or undef if none such exists.

   retrieve DOMAIN KEY
       Returns a Jifty::CAS::Blob for the given pair of "DOMAIN" and "KEY", or undef if none such exists.

   memcached_config
       Returns a hashref containing arguments to pass to Cache::Memcached during construction. The defaults are like:

	 {
	     servers	 => [ '127.0.0.1:11211' ],
	     debug	 => 0,
	     namespace	 => Jifty->config->framework('ApplicationName'),
	     compress_threshold => 10240,
	 }

       To change these options, set them in your Jifty application config file under "/framework/CAS/Memcached" like so:

	   framework:
	     CAS:
	       BaseClass: 'Jifty::CAS::Store::Memcached'
	       Memcached:
		   servers:
		       - 10.0.0.2:11211
		       - 10.0.0.3:11211
		   compress_threshold: 5120

   memcached_fallback
       Returns a boolean (from the config file) indicating whether or not memcached should fallback to the per-process, in-memory store.

NAME

       Jifty::Web::Session - A Jifty session handler

SYNOPSIS

       In your etc/config.yml (optional):

	 framework:
	   Web:
	     # The default ($PORT is replaced by the port the app is running on)
	     SessionCookieName: JIFTY_SID_$PORT

   new
       Returns a new, empty session.

   id
       Returns the session's id if it has been loaded, or "undef" otherwise.

   create
       Creates a new row in the Jifty::Model::Session table.

   load [ID]
       Load up the current session from the given "ID", or the appropriate cookie (see "cookie_name") otherwise.  If both of those fail, creates a
       session in the database.

   load_by_kv key => value
       Load up the current session from the given (key, value) pair. If no matching session could be found, it will create a new session with the
       key, value set.	Be sure that what you're loading by is unique. If you're loading a session based on, say, a timestamp, then you're asking
       for trouble.

   get KEY [TYPE]
       Returns the value for "KEY" for the current user's session.  "TYPE", which defaults to "key", allows accessing of other namespaces in the
       session, including "metadata" and "continuation".

   set KEY => VALUE, [TYPE]
       Sets the value "VALUE" for "KEY" for the session.  "TYPE", which defaults to "key", allows values to be set in other namespaces, including
       "metadata" and "continuation". "VALUE" can be an arbitrary perl data structure -- "Jifty::Web::Session" will serialize it for you.

   remove KEY, [TYPE]
       Remove key "KEY" from the cache.  "TYPE" defaults to "key".

   remove_all
       Removes the session from the database entirely.

   continuations
       Return a hash of all the continuations in this session, keyed by the continuations' "id".
