14.4.3. Keeping Page and Session State
VSPX does not require any particular session management to be in effect to operate. It is in its default form entirely stateless on the server side. There is a mechanism called view state for keeping track of data between consecutive post backs of a single page. This is simply an automatically maintained hidden field which will keep the state of controls which have a state that may be persisted. The view state mechanism does not however safeguard data across different pages but is fine for remembering entered form data or a bookmark in a scrolled list across page reloads.
To keep real sessions and session variables, a
v:login
control is offered.
