Last week, while backing up the site, I stumbled upon the access log and noticed a few hits from internal sites at apple.com. Which is nothing much - it happens every now and then, and folk from Microsoft, Sun and a few other places are regular visitors.
Looking back through my server log, I found a number of similar URLs (apparently part of a Confluence site that believes itself to be da.apple.com) with a number of interesting pathnames (one of which contained the word Trident, for those of you fond of conspiracy theories).
Anyway, just in case, I'll be filtering apple.com from my Referrers list as well (who knows, it might be secret, and their secret is safe with me).
Just after I come back from the pool, that is.
