Package org.appng.core.controller.filter

Class MSOfficeUserAgentFilter

java.lang.Object

org.appng.core.controller.filter.MSOfficeUserAgentFilter

All Implemented Interfaces:

javax.servlet.Filter

public class MSOfficeUserAgentFilter
extends Object
implements javax.servlet.Filter

This Filter is a workaround for a bug in Microsoft Office which causes the http-session to get lost if a link is being opened from inside a Microsoft Office document.
See KB 899927 for details.

The solution is to send a meta refresh if MS Office is detected as user-agent.

To enable this filter, add this to the web.xml:

 <filter>
  <filter-name>MSOfficeUserAgentFilter</filter-name>
  <filter-class>org.appng.core.controller.filter.MSOfficeUserAgentFilter</filter-class>
 </filter>
 <filter-mapping>
  <filter-name>MSOfficeUserAgentFilter</filter-name>
  <servlet-name>controller</servlet-name>
  <dispatcher>REQUEST</dispatcher>
 </filter-mapping>
