I have a web application which is specifically configured to use Fiddler as it's proxy in Web.Config independently of the setting of the system proxy. I am only interested in the traffic from/to this application so would prefer not to have the system proxy changed.
If I uncheck the option "Act as system proxy on startup", Fiddler starts, but isn't capturing. If I start capturing, it changes the system proxy.
If I change the system proxy using Settings, Fiddler pops up a yellow bar saying "The system proxy was changed. Click to reenable captuing". If I click, it starts capturing, but changes the system proxy again.
How do I tell Fiddler to start capturing but not to change the system proxy, i.e to only capture traffic from applications which specifically use it as a proxy?
