As you all know we can easily get duration details of an HTTP request by using ClientTrace. Like DNS time, TTFB, etc. But what if I use a proxy server while sending the request? As far as I know, ClientTrace does not have a hook for calculating the proxy server latency. Is there any other way to eliminate proxy server latency from the total request duration?
What I want to achieve;
Life cycle without proxy;
Client --- request_duration ---> Server
Client <-- response_duration --- Server
Life cycle with a proxy;
Client --- request_proxy_latency ---> Proxy --- request_duration ---> Server
Client <-- response_proxy_latency ---- Proxy <-- response_duration --- Server
In both cases above I want to calculate only request_duration + response_duration.
