Beats me. Only asked for, and got, favicon.ico.

Been doing this for 6 months. Also requests RSS XML feeds.

Yahoo is doing some dumb things at the moment. For the past week they've been sending round some kind of mobile hit - not sure if it's a crawler or a proxy but I suspect the latter. No UA, no referer, no headers, not even X-FORWARD.

68.180.211.nnn ycar5.mobile.sp1.yahoo.com (USA)
209.131.38.nn ycar6.mobile.sp1.yahoo.com (USA)
87.248.122.nn ycar2.mobile.ch1.yahoo.com (Swiss)

Generally one at a time but at one point the 68 and 209 ones hit the same site within a second.

I've seen "ycar" as well. It stays off the whitelist until its provenance and purpose are established...
