Can you use DataReductionProxySettings::IsDataReductionProxyEnabled?  It will be
hard to keep them in sync.

[Feng Qian, 2014/07/17 20:00:13]

There is an threading issue. Correct me if I am wrong.
DataReductionProxySettings::spdy_proxy_auth_enabled_ cannot be accessed from IO
thread. ProfileIOData::data_reduction_proxy_enabled_ can only be accessed from
IO thread.

I am just afraid someone may forget to change this when making changes  under
components/data_reduction_proxy. Ben will maintain the code there. I am fine as
long he is fine with this.

Ben, can you take a look?
