tusd example with behind proxy

[G2G2G2G]

Currently the example https://github.com/tus/tusd/tree/master/examples/server seems to lack virtually every option the binary does, and not much info about how the binary works and no methods to build certain parts of it in the example.

Nearly 1/4th the issues posted here are proxy related, and I keep triggering this issue https://github.com/transloadit/uppy/issues/2285#issuecomment-632920770 and the best methods to config stuff seem to be block tusd and uppy and rewrite the headers aspects.

So how do I read the x-forward headers in the tusd example and respond with the location header that uppy uses?
