Configuring Fiddler to capture sessions between two local IISExpress sites?

Question

Is there a way to configure Fiddler 4.6 to capture traffic from one instance of IISExpress running on my Dev machine to a second IISExpress instance running on the same Dev machine?

I am using VS 2017 with one web site that is accessing some Web API methods on a second site running on another instance of IISExpress.

All of the browser to server traffic is captured fine, but I need to go from site to site to test some API calls.

The question is not so clear, but if you wants to communicate one IIS with another, you need to add a proxy like in the example:

var httpClientHandler = new HttpClientHandler
                        {
                            Proxy = new WebProxy("http://localhost:8888", false),
                            UseProxy = true
                        }

For more info take a look at the Fiddler docs
