I just took a look at this myself. I threw up a page yesterday, simple html with a table and 5 images.
Emailed the link to a chick. (Pics of me - no, not that kind.)
I checked the logs to see if she had viewed it, and I got:
spider-mtc-ti023.proxy.aol.com - Got the html page.
spider-mtc-ti023.proxy.aol.com - got the first image.
cache-mtc-af06.proxy.aol.com - got the second image.
spider-mtc-ti023.proxy.aol.com - the the third image.
cache-mtc-ah02.proxy.aol.com - got the fourth image.
spider-mtc-ti023.proxy.aol.com - got the fifth image.
So three different machines got the page/images. No rhyme or reason I can see.
What I would like to know is, what kind of requests (if any) would I get for another user today. I would test it myself, but can't bring myself to installing AOL - just... can't... do... it.
Anyone have AOL installed and want to test this? (Don't be ashamed - just for SEO testing, right? ;) )
