UMA data collector for cross-site documents(XSD) Intercept cross-site documents and apply a couple of blocking filters to measure how our cross-site document blocking policy affects the renderer behavior. This doesn't actually block anything, but just records UMA data about how these filters work. It does three things: 1) whitelists legitimate XSDs (responses with whitelisted mime types or with valid CORS headers) 2) applies an appropriate content sniffing algorithm depending on the mime type of the response, 3) if it is sniffed as a blocked document, reports its status code and the context (img, script, etc) where the request is originally issued to measure the compatibility impact of the blocking.
