I have wireshark but it doesn’t show anything that uses loopback interface L
OK. I've setup a test environment here and I can reproduce the problem. I can connect to the server we start using IE (though I get "Unauthorized" back as I don't know the random access key), so it seems that for some reason the runtime/QtWebKit is not paying attention to the exclusion addresses or the "bypass proxy for local addresses" options, despite picking up the other parts of the config.
