Spring Security Session Timeout - Clear Browser Cache - spring

Question

I currently have a web application that is utilizing Spring Security hosted on a JBoss 5 server.
My issue is that if a user is idle for a few minutes then their session times out due to web.xml setting. Once in a while they when try to hit the webapp when their session is invalid they get a 404 error. The only way the browser can see the web app is when the user clears their browser cache.
Is there a way a fix for this so that the user doesn't have to clear out their browser cache?
Here is my spring security xml
<security:http auto-config="true" use-expressions="true">
<security:intercept-url pattern="/login" access="permitAll" />
<security:intercept-url pattern="/resources/**" access="permitAll" />
<security:intercept-url pattern="/import/trades" access="permitAll" />
<!--
The roles are prefix with the word ROLE
and it is upper case due to ldapAuthoritiesPopulator config section
-->
<security:intercept-url pattern="/**" access="hasAnyRole('ROLE_NBFIEPN_USERS', 'ROLE_NBFIEPN_DEVELOPERS')" />
<security:form-login login-page="/login" authentication-failure-url="/login?error=true"/>
<security:logout />
</security:http>
Here's my web.xml file. I have currently set the session timeout to 1 minute to replicate the issue.
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

Add this configuration to your spring security configuration
<security:http...>
...
<security:session-management invalid-session-url="/login"/>
</security:http>
Desription for invalid-session-url parameter:
The URL to which a user will be redirected if they submit an invalid session indentifier. Typically used to detect session timeouts.
It should guid the user with an invalid session to the login page.
