the "authentication" module works in the sessions system so that once finished the identification process, the system assigns the user a "session-ticket" that is valid until any of the following circumstances take place:
-. the user closes the navigator application.
-. the user cancels the session voluntarily clicking on the "log out" URL.


the process of creating a page and/or link to end the work session is described below.

0.0.- in Dreamweaver®, open the PHP_GenB dynamic page that you want to use to end the session or the page where you want to insert a "logout" link.

1.0.- from the "Server Behaviors" panel select "Authentication: Log Out User":

1.1.- enter the parameters requested by "Authentication: Log Out User":

1.2.- Log Out When (end session when): Type of log out control:

-. Link Clicked
-. Page Loads

NOTE: there are two ways to end the session:

-. when you want the user to go to a "good-bye" page to end the session, the best option is to construct a

"Log Out" page, which, when presented to the user, ends the session "Log Out When: Page Loads". This way, the user can end the session anywhere, by a simple "link" to a Log Out page.

-. when you want the user to go to an outside page or simply to a page not devoted explicitly to the "good-bye" process to end the session, the best option to choose is a logout process "Log Out When: Link Clicked".


1.3.-When Done, Go To (when the session is over, go to): URL of the destination page to which you are sending the user when the session is over (good parameter for the option "Log Out When: Link Clicked").


in the next chapter, the use of session variables is described session variables.
