On many IE 10 tests, I’m seeing extraneous requests to https://urs.microsoft.com/urs.asmx and/or https://t.urs.microsoft.com/urstelemetry.asmx
A quick Google search of these resources suggests that they are part of IE 10’s anti-phishing feature. Searching the forums shows some similar issues in the past with other browsers and the conclusion was also something to do with phishing/malware filtering.
Is this a known issue?
