contextRelative locations

Is it possible to specify context relative (similar to struts global
forward's contextRelative) equal to true such that locations starting
with "/" will have a "root" of treated as 
http://host/<context>/

Rather than 
http://host/

The issue I am having is that I have a large menu structure that I would
like to use in multiple places within a multi-module application (one
parent struts-config and 3 children). The layout of the site is as
follows:
/
/mod1
/mod2
/mod3

My desire is that when a user requests:
http://host/<context>/
http://host/<context>/mod1
http://host/<context>/mod2
http://host/<context>/mod3

They receive the same menu, but if I specify locations such as
location="mod1/page1" they will not work when displayed within the
modules as the URL becomes if in mod1:
http://host/<context>/mod1/mod1/page1

if I specify locations such as location="/mod1/page1" they will not work
when displayed within the modules as the URL becomes:
http://host/mod1/mod1/page1

Note the missing <context> which I cannot hard code as it changes as we
roll through our environments from development through to production.

Any ideas?
