I kept running into problems where requests coming from Apache looked like:
GET /foo//bar instead of GET /foo/bar

Unfortunately this was causing NPEs and resource not found errors in a third party servlet filter we are using to combine some our static resources. This is the Apache configuration that seems to have resolved the problem, I just wanted to post it here in case I ran up against it again.

# Placed in Apache conf for the site
<Proxy balancer://app_cluster >
BalancerMember http://app1/foo
BalancerMember http://app2/foo
BalancerMember http://app3/foo
</Proxy>
ProxyPass /foo/ balancer://app_cluster/ stickysession=JSESSIONID
ProxyPassReverse /foo/ http://app1/foo/
ProxyPassReverse /foo/ http://app2/foo/
ProxyPassReverse /foo/ http://app3/foo/

The lesson here is attention to detail, especially your final slashes.
