UnXF - Un-X-Forward* the Rack environment
Rack middleware to remove “HTTP_X_FORWARDED_FOR” in the Rack environment
and replace “REMOTE_ADDR” with the value of the original client address.
This uses the “rpatricia” RubyGem to filter out spoofed requests from
clients outside your LAN. The list of trusted address defaults to private
LAN addresses defined RFC 1918 and those belonging to localhost.
This will also read “HTTP_X_FORWARDED_PROTO” and set “rack.url_scheme” to
“https” if the “X-Forwarded-Proto” header is set properly and sent from a
trusted address chain.
If you use RubyGems:
gem install unxf
You will need a C compiler and Ruby development headers to install the
“rpatricia” RubyGem if it is not already installed.
You can get the latest source via git from the following locations:

Inline patches (from “git format-patch”) to the mailing list are preferred because
they allow code review and comments in the reply to the patch.
We will adhere to mostly the same conventions for patch submissions as git
itself. See the Documentation/SubmittingPatches document distributed with
git on on patch submission guidelines to follow. Just don't email the
git mailing list or maintainer with unxf patches.
All feedback (bug reports, user/development discussion, patches, pull
requests) go to the mailing list: email@example.com
