rb:marksession
Mark all anchor and src tags with session ID BodyThe rb:marksession body is empty. RemarksThe WhitebeamPresentation Engine provides all the necessary logic
to track user sessions and to allow Pattern Pages
to store information against those session. For this facility to work the Presentation Engine
must plant a session identification value on the clients machine in such a way
that the browser will return that ID to the engine with the next request. The
Presentation Engine always attempt to plant a browser cookie containing the value
back with the client. This works fine for all clients that have cookies enabled (the majority).
and if a site is happy with this then nothing else is required. If the client disables cookies for some reason a different strategy is required. Generally
the process involves adding the ID to any site referencing URLs and to add 'hidden'
form values to forms. The engine can do all the real work for this simply by the
web author adding the marksession
attribute to all elements that refer back to the same site. This can however be tedious - the rb:marksession tag can be placed once
anywhere in a Pattern Page - or a page included - and it will mark all anchor, image
and form tags that are appropriate with the session ID.
An element suitable for tagging must have a URL in an 'href' or 'src' attribute
that includes no prototol part (must not start with http). To force the Presentation
Engine to avoid marking a reference explicitly - make use the URL starts with
'http:'.
