Frequent Strange Requests

["Auke Rensen" <auke@rensen.dyndns.org>]

L.S.,

While scanning my Apache Access logs I recently discovered that my webserver
gets some strange requests. While just guessing I can say I get these
requests about 10 to 25 times a day.
My site is just a personal site, no commercial activities are done here.

Can anybody tell me what this is, whether to worry about it and what to do
about it.

Thanks in advance,
