Created attachment 228392 [details] Screenshot from Safari's inspector Version: Version 7.0.3 (9537.75.14) Requst inspector in Webkit is missing the 'Authorization' header responsible for auth-basic authentication to websites. Thus it is hard to debug this with the inspector. Two screenshots showing the difference, once from Safari and once from Chromium.

This is a limitation of CFNetwork, which WebKit uses for networking. They add most of the headers and we don't know what they add at the WebKit level. We have a request internally to add such a capability.
