I was looking at my server logs for Apache, when I can across a few websites which were accessed through my site. (At least, that's what I'm taking it to mean. You can see the image below. There were requests in the logs for things like
http://texan.homeunix.nethttp://www.ebay.com) Was I right in my interpretation of this and what can I do to prevent it/does it even matter?
The image is from a log analyzer which I use: (the two wesites are highlighted in red.)
