Filtering requests to /portal context

[troy.sellers]

Hi All,

Can someone let me know how I would get a servlet filter working to filter /portal requests? I want to intercept these requests before they get to the portal.

Is this possible? Is this a good idea? Where can I find out about strategies for doing this kind of thing?

Cheers,
Troy

Just to narrow this question.

I have created my servlet filter and have updated the web.xml file in the portal-server.war directory.

The filter entry

 <filter>
 <filter-name>mobileFilter</filter-name>
 <filter-class>com.axegroup.jboss.servlet.filters.MobileDeviceFilter</filter-class>
 </filter>
 <filter-mapping>
 <filter-name>mobileFilter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>

This works, in that it calls my class before processing the portal request.
However, I want to apply this to context /portal and all children of this.
When I enter the

 <filter-mapping>
 <filter-name>mobileFilter</filter-name>
 <url-pattern>/portal</url-pattern>
 </filter-mapping>

context in the mapping my class is no longer executed.

Any ideas here?

Cheers,
Troy
