Https proxy in front of jetty doesn't work very well.

It is not a bug in continuum, but in Jetty. The continuum system relies heavily on sendRedirects. Jetty however makes the Location http header an absolute url instead of a relative url. The simple fix is to add a filter to override sendRedirect. I made this filter (I have this fix available), but before it could end up in continuum it is best to have a more generic solution or make it configurable to use to filter or not (in case of issues in other containers, which I haven't tested yet).
Feedback welcome.

Not asking for a fix, I will provide it and will use this issue to track it and also add documentation on how to set this all up.
