Thanks. I understand that. I&#x27;m trying to pass files efficiently, with less bandwidth. It&#x27;s so I can pass all the info to my phone without paying so much for the data plan. I&#x27;m talking about all forms of data. The proxy is for the relay between the server (C) and the proxy (B) and my phone (A). I want to very quickly use B to download from C and send in the smallest way I can to A. I&#x27;ve been working on a two way hash for years with no success. I&#x27;m trying to make a service that will let phones use less data on their data plans. That&#x27;s the efficiency I&#x27;m looking for.
