Sorry, I apparently didn't make myself clear.  I know what the Link
method does and what 501 means. What I don't know is why these
requests come in every three hours, and what they're trying
to accomplish.  Is it just a poll to see if any meta information
has changed at the site?  I'd like to filter these out of my logs,
but not until I assure myself that they aren't of any consequence,
security-wise.

Thanks.
