Hi guys,

I'm using different proxies for each browser, let's say 5 different proxies/IPs.

The question is: How to make the fiddler classic capture the traffic (requests/responses) from all the browsers? It means that it should read the traffic from 5 proxies at the same time.

Hello Ararad,

 

You could try the other way around - set all browsers to go through the Fiddler proxy and then let Fiddler change the gateway based on custom logic through FiddlerScript. For example, use the OnBeforeRequest event to direct the traffic to a different gateway based on the process (that generates the traffic).

if (!oSession["X-PROCESSINFO"] || !oSession["X-PROCESSINFO"].StartsWith("MyProcessName")) {
    oSession["x-OverrideGateway"] = "gateway:port";
}

This perfectly works for each browser process. It cannot handle normal/private mode, but still - this filled the need. Thank you Nick!
