Hi! Please find attached net-proxy/tinyproxy-16.5.ebuild and a patch so that can optionaly remove the HTTP_VIA header Reproducible: Always
Created attachment 209855 [details] tinyproxy 1.6.5 ebuild
Created attachment 209856 [details, diff] HTTP_VIA header removal patch
Fixed in cvs, but the name of the USE flag has been renamed http-via-header and it is enabled by default (normal vs negative logic).
