Hello Amos, This is the via header sent by my local proxy as part of the request. *Via: 1.1 ubuntuozgen (squid/3.5.19)*
It is not fqdn but ubuntu concatanated with a Turkish name so it is highly unlikely that yahoo have such named reverse proxy. I could not decrypt the squid <--> flicker traffic yet this is from pcap output from another http site but i think it should be same right? Thanks.
