While looking at my server's logs for 404 error codes I've noticed a limited number of nonsensical-type errors.
I see "GET" requests where my server's normal file structure is combined with "file" names such as "info(dot)com" or FreeDictionary(with no file extension).
In other instances it is clear that the 404 calls are to files associated with Kontera (in-text advertising) (files like KonaBase.js) but have mistakenly been looked for on my server, not theirs.
These errors are few and far between but I do seem to see some each day. I'm kind of assuming these types of server errors are relatively common and will always exist to some degree but I'm not sure.
In regards to what I think may be associated with this problem, I do use a
<base href="http://www.example.com/">
tag on each page.
I also use Adsense and Kontera advertising on these sites, both of which are .js intensive it seems.
Are these types of events expected to occur (although infrequently) or do I have some type of problem?
