<filter-mapping>
<filter-name>PicketBox Delegating Filter</filter-name>
<url-pattern>/picketbox_logout</url-pattern>
</filter-mapping>
To logout your users PicketBox provides a specific path: /picketbox_logout.
After configuring the PicketBox Security Filter in the web.xml, add the following <filter-mapping> configuration:
<filter-mapping>
<filter-name>PicketBox Delegating Filter</filter-name>
<url-pattern>/picketbox_logout</url-pattern>
</filter-mapping>
Now you can redirect your users to this path and start the logout process.
