I have a WordPress website with AWS on use, namely the Cloudfront service, to serve CSS, images and JS from the cloud.
Lately, I noticed a lot of hits from bots coming from :
Goeip trace them to Ashburn, USA. They crawl all the RSS feeds of my website (posts, categories), almost every minute, coming from https://www.google.com/.
Their user-agent are a bit random :
Browser: undefined Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9a3pre) Gecko/20070330
Browser: Chrome version 0.0 running on MacOSX Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1309.0 Safari/537.17
Browser: undefined Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:220.127.116.11; ) Gecko/20101203
How can I find out what they want ? Are they related to the cache generation for Cloudfront ?
