The error appears in Web Inspector and no corresponding HTTP request appears in the web server logs. I stepped through the execution in Safari 5.0.3, and the click handler is triggered. This is a significant issue that impacts major apps like Google Analytics. The only workaround appears to be setting the anchor's target attribute so that the page loads in a new window, e.g., target="_blank". Opening a new window disrupts the user experience and is frowned upon.

Did you test with nightly builds from <http://nightly.webkit.org>? I think that some of these ping mechanisms should work now.

Created attachment 83075 [details] Another example with beforeUnload handler Added a beforeUnload handler to the example to introduce a delay, in case the ping request was being interrupted by the default action due to some timing issue.

The only difference with the latest nightly (r78800) is that Web Inspector went from: Failed to load resource. to: GET http://url-of-ping-request undefined (undefined)

Please re-open if this is still an issue in nightly builds.
