I hope you're experienced with reverse proxies and the implications. We
generally don't recommend this as users tend to underestimate the impact
and also the Icecast code base is not prepared for being behind a
reverse proxy. In addition to what you see, e.g. your access.log and
some of the admin pages will be rather useless, listing ::1 or 127.0.0.1
as the origin address of all connections.
We are considering how to make Icecast more suitable for reverse proxy
setups. So your input is certainly welcome.

The latest Icecast stable version is 2.4.1, we strongly recommend using
that due to previous security issues and tons of bugfixes.
Development patches are preferably against git head. Details how to
check out can be found here:

Please send patches as attachments, HTML mails tend to malform them.
Also preferably use plain text emails on mailing lists.
