Looks to be pretty simple change to the Engine implementations. I'll just commit into master, as it will be disabled by default and is testing fine with mod_perl and CGI. Setting to merged.
Currently I have a Configure checker put up a warning if it detects a proxy. Should bootstrap automatically enable the header processing if it discovers foswiki is behind a proxy?

This feature is much too important not to release it ASAP. Basically we cannot use Foswiki behind a reverse proxy ... which is very much best practice deploying Foswiki using Docker.
I will backport it to the 2.1.8er release.
