For one of my projects I am using Fiddler ( ) to trace my http request. I have noticed some strange calls (screenshot) to some weird URLs whenever I start Chrome (Version 23.0.1271.1 dev-m) .

I have disabled all extensions, because this was my first idea - the calls persist. Any ideas what these calls (screenshot 3,4,5) are?

That is OK. Google Chrome at startup makes 3 request to random domains. The goal of the requests is to determine if you’re currently on a network that intercepts and redirects requests for nonexistent hostnames. You can read more in that article
