[xwiki-users] how to use xwiki behind an authenticating http proxy?

Hi, I'm trying to set-up xwiki for my company but I have an issue with our authenticating http proxy which prevents me to install additionnal plugins into xwiki. I searched the FAQ and mailing list archives but could not find a reference to how to use xwiki behind an authenticating proxy (I could only find information on how to use it behind a reverse proxy). I tried to setup the usual JVM properties http.proxyHost, port, username and password but xwiki does not seem to use them. The error stacktrace shows a connection timeout in the HttpClient classes. So I'd be glad to know if xwiki can be used behind such a proxy, because it's currently a showstopper for us (and I REALLY would like to use xwiki instead of mediawiki).
