We're moving a customer from using SOAP Proxy objects to HTTPClient calls.

It's be productive if we could capture the outbound SOAP requests with FIDDLER 4. 

We see the newer prototypical HTTPClient requests, but the legacy outbound SOAP WS proxy don't appear in the Fiddler log.

How do we configure Fiddler to "see" these outbound requests?

It appears that Fiddler listens on/to port 8888 by default.

If this is what needs to be modified...to what value please?

Any other Fiddler settings to which we need to pay attention?

Thank you.
