data compression proxy

[asmadeus08]

Google's data compression server needs authentication.Authentication string should be provided in google_api_keys.cc

Code:

 std::string GetSpdyProxyAuthValue() {    return "ac4500dd3b7579186c1b0620614fdb1f7d61f944";    /* #if defined(SPDY_PROXY_AUTH_VALUE)    return SPDY_PROXY_AUTH_VALUE; #else    return std::string(); #endif   */  }

And the returned version should be correct Chromium version in data_reduction_proxy_request_options.cc

Code:

std::string DataReductionProxyRequestOptions::ChromiumVersion() const {  return "44.0.2403.157";  /* #if defined(PRODUCT_VERSION)  return PRODUCT_VERSION; #else  return std::string(); #endif  */ }

Can i do it by myself on SlimJet or on Vivaldi qand where is i can find that file and how to compile code? Please can you explain?
