iwb behind proxy

[neteducation]

Hi all,

I want to run an IWB behind a reverse proxy, i.e.

https://www.mycompany.com/iwb going to the proxy server which then in the background proxies to https://iwbserver.mycompany.com:50443/

Currently most of the links are absolute, though not fully qualified, i.e. <link rel='stylesheet' href='/stylesheet_fiwb.css' type='text/css' />

This then makes the browser request https://www.mycompany.com/stylesheet_fiwb.css but it should actually go to https://www.mycompany.com/iwb/stylesheet_fiwb.css

How can I specify the base url ?

Thanks

Frank
