Right, which is what I would expect, and what I used to get in my webapps.

I used Filters in my current webapp (which is exhibiting the bizarre behaviour) previously
and the Filters used RequestDispatchers. However, I've since removed the filters. 

OK, I just solved it - I completely deleted the "work" directory of Tomcat and restarted Tomcat
and now it seems to be working correctly. Sorry for the noise :(

Can I please check the following then,

If a Filter makes a call to a page using for example RequestDispatcher.forward("/Products/index.jsp"),
will that request dispatcher bypass any filters, or will it still be subject to all filter
rules ? 

Sorry for the noise. I don't know why I was getting the strange results. Even if a Filter
was being cached in 'work' (even after restarting Tomcat), it shouldn't have been called at
all because I'd removed all the Filter-mappings from web.xml
