NAME
MasonX::Request::WithMulti2Session - Multiple sub-sessions within one "parent" session
SYNOPSIS
PerlSetVar MasonRequestClass MasonX::Request::WithMulti2Session
DESCRIPTION
MasonX::Request::WithMulti2Session is experimental ( beta ) and should only be used in a test environment.
MasonX::Request::WithMulti2Session is a clone of MasonX::Request::WithMultiSession changed to work under a pure mod_perl2 environment. The external interface is unchanged, see MasonX::Request::WithMultiSession.
The actual changes I made can be found in the distribution in diff/WithMultiSession.diff ( made with 'diff -Naru' ... ).
A HOWTO for MasonX::Apache2Handler and friends may be found at Mason-with-mod_perl2.
The following documentation is from MasonX::Request::WithMultiSession.
This module subclasses MasonX::Request::WithApache2Session
in order to allow multiple "sub-sessions" to exist within one parent session.
This can be quite useful for a web app where you want to allow the user to open multiple windows, each with a different session, but session ids are stored in a cookie.
Like MasonX::Request::WithApache2Session
, sub-sessions are shared between a request and any subrequests it creates.
METHODS
This class has an interface quite similar to that of MasonX::Request::WithApache2Session
.
session
The primary interface to this class is through the
session()
method. When this method is called without any parameters, the module looks for an existing sub-session specified by the sub-session id argument parameter (which can be in a query string or POST). This value can be overridden by explicitly passing a "sub_session_id" parameter.If this parameter is found, an existing sub-session is returned. If this parameter is not found, a new sub-session is created.
If the
session()
method is called assession( clone => 1 )
then a new sub-session will be created, and its contents will be the same as that of the current sub-session. This is a shallow copy of the old session hash, so objects and references are shared between them.If
session( new => 1 )
is called, then a new, empty, sub-session is created.You can specify the main session id to use via the "session_id" parameter.
sub_session_id
This method returns the currently active sub-session's id. Use this method to put this id into URL parameters, forms, etc. as needed.
If given a "sub_session_id" parameter, it will set the current sub-session id.
delete_sub_session
By default, this simply defaults the current sub-session. You can pass a "sub_session_id" parameter to delete a specific session.
Parameters
This module takes two parameters besides those inherited from MasonX::Request::WithApache2Session
:
multi_session_args_param / MultiSessionArgsParam
This parameter can be used to specify which parameter contains the sub-session id. By default, the module will look for a parameter called "sub_session_id".
multi_session_expire / MultiSessionExpire
This parameter specifies the number of seconds after a sub-session is accessed until it is purged. If not specified, then sub-sessions are never purged.
Sub-sessions expiration is checked when the request object goes out of scope.
USAGE
You will need to manually set the sub-session id argument parameter for each request. The easiest way to do this is to make sure that all URLs contain the sub-session id. This can be done by using a <%filter>
block in a top-level autohandler (although this won't catch redirects), or by making sure all URLs are generated by a single component/function.
