altering the request URI in a filter

Hi,

Tomcat 404, jdk1.3:

Is it possible to alter the request's URI after authentication but 
before the request is delegated to a Struts action mapping?

I would like to be able to strip a string from the request URI which is 
there solely for the purposes of enforcing the web container to obtain 
authentication and authorization info. (if the web container's auth 
cache has been turned off).

Cheers
jfc

Hi,

Thanks for the reply. How can I actually set the new value/s on the 
request? I don't see any setter methods or any fields which can be used 
to hold the new value.

The only setters I can see are setAttribute and setRequest.

The beauty of Filters is that anything is possible :-).  The Filter (at
least under Tomcat) will only be invoked after authentication, but before
the Struts servlet.

You would need to wrap the Request with one that over-rides (at least)
getRequestURI, and getServletPath, and in some cases, getPathInfo (although,
since Struts uses extension mappings, the last one shouldn't apply in your
case).
