data compression proxy

[Admini]

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 */ }
