Controlling authentication on multiple contexts which point to the same webapp

[Jason Saunders]

If you have multiple contexts which point to the same webapp, is there a way
of only applying authentication to specified contexts?
 
e.g. something along the lines of;
 
<Context path="/webapp1"
 docBase="/webapps/a_web_app"
 authenticate="true"
 etc...
 </Context>
 
<Context path="/webapp2"
 docBase="/webapps/a_web_app"
 authenticate="false"
 etc...
</Context>
 
Since the authentication is controlled by the WEB-INF/web.xml file,
alternatively is it possible to specify different web.xml files per context.
 
Many Thanks
