I noticed in my apache logs that I was getting a lot of traffic from my own site. I've tracked it down to times when I do an edit on a published post. When I save the edit, I get a "loading" indication on the admin page, and see every single self-referenced link in the post accessed. I have perhaps 50 links to a script which redirects to external links, and each one is tried in a serial manner. What's up with that? At times, it's tried as a HEAD, then as a GET. How do I stop this behavior?
