I have installed Jenkins on our Redmine instance but cannot get the mod_proxy config working.

I tried adding the following to apache2.conf:

ProxyPass         /jenkins  http://localhost:8081/jenkins
ProxyPassReverse  /jenkins  http://localhost:8081/jenkins
ProxyRequests     Off

# Local reverse proxy authorization override
# Most unix distribution deny proxy by default
# (ie /etc/apache2/mods-enabled/proxy.conf in Ubuntu)
<Proxy http://localhost:8081/jenkins*>
  Order deny,allow
  Allow from all
</Proxy>

It seems that all requests end up in in the ROOT app.
