de.kune.sessionxs.SessionMatcherFilter

All Implemented Interfaces:

javax.servlet.Filter

public class SessionMatcherFilter
extends Object
implements javax.servlet.Filter

This class initializes and invokes session matchers and handles any matching failure. The session matcher filter can be used in the web.xml file like this:

        <filter>
        <filter-name>SessionMatcherFilter</filter-name>
        <filter-class>de.kune.sessionxs.SessionMatcherFilter</filter-class>
        <init-param>
                <param-name>session-matchers</param-name>
                <param-value>de.kune.sessionxs.matcher.ClientIPAddressMatcher</param-value>
        </init-param>
        <init-param>
                <param-name>failure-handler</param-name>
                <param-value>de.kune.sessionxs.failurehandler.InvalidatingSessionMatchingFailureHandler</param-value>
        </init-param>
 </filter>
 
 ...
 
 <filter-mapping>
        <filter-name>SessionMatcherFilter</filter-name>
        <url-pattern>/*</url-pattern>
 </filter-mapping>
