Thanks All, using PerlOutputFilterHandler gives me the desired result for the pages in htdocs for the <Location ...> specification.. [using the inputs from this group and http://www.gossamer-threads.com/lists/modperl/modperl/104437].
Now I am noting that my earlier integration of Apache with JBoss where I am redirecting based on certain paths is not working. If I remove the output filter the jboss page shows, but when I put it (httpd.conf) the display of dynamic content from Jboss stops. E.g. in mod-jk.conf: JkMount /jspweb/* node1 What am I missing here? Many thanks for your inputs in advance!

By using this method we are able to wrap, static content, output from other mod_perl handlers, php scripts, ruby scripts, output from others servers - tomcat servers behind mod_jk other perl servers using mod_proxy... All with a common method... not seen any "adverse" effects with performance.. James
