Review Comment:
I have followed the method used by lua-resty-openidc library, i.e try to
extract from `Forward` header first, then look at xfh otherwise fallback to
`http_host` value. You can find that here:
https://github.com/zmartzone/lua-resty-openidc/blob/fabf64e29062f5e7658de1cee52f572221203b1e/lib/resty/openidc.lua#L271-L275
