           Summary: Implement <a ping>
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jam at chromium.org


Creating a bug from the webkit-dev discussion.  It seems there's consensus on
doing this.  The main reasons are that without a robust way to handle tracking,
ad networks and other sites are resorting to redirects and busy loops in unload
handlers after image loads.  This hurts the user since it slows down their
navigation and consumes battery on mobile/laptop devices.  Adding ping doesn't
reduce the privacy, since it's something that's already done using hacks.  This
should improve privacy since user agents can then expose options to the user to
disable this feature, just like for referral headers.

This is part of HTML5:

Note: once we do this, there are a few people who think we should implement
window.sendPing() as well.  The reasons are that <a ping> won't work for
iframes, which is how it's used by ad networks.
