I have a bunch of these in my nginx log file, on a range of URLs:on 66.102.9.23 - - [12/Nov/2015:10:40:25 +0000]     GET /myadminfolder/page.html HTTP/1.1 200 1247 1800     - Google favicon 111.111.111.111Where 111.111.111.111 is my home IP address.(Whatever it is isn't logged in so thankfully it gets bounced to the login page after this.)I don't fully understand these, what they are or why they happen.  I looked the IP address up and it does appear to be google (http://www.dnsstuff.com/tools#ipInformation|type=ipv4&&value=66.102.9.23).My admin folder is secret and not linked anywhere (security through obscurity...).  That and my IP address suggest it must be something to do with my Chrome browser, I guess?I've not accessed that page myself since 22 hours prior to this log though, so it's certainly not something that happens AS I browse.Can someone tell mewhat this isWHY it isif I should be worried about it!?Thanks!
access.log requests from UA Google favicon...? What do these mean?
