How to set base path

Hello,

I try to set up YouTrack.
I place apache in front of YouTrack jar, and configure apache mod_proxy.

I have to set proxy on path '/youtrack' because the apache is a proxy of other services.

for example:
http://develop.example.com/youtrack  – apache proxy
http://localhost:8080 – YouTrack jar proccess

There is a problem. This YouTrack return the page as the base path is '/'.
What is parameter of base path or other configurations?

Thank you.
