I keep on getting 404 errors on http://ombelico.de which are caused by the User-Agent "RSSOwl/1.0 (Windows; U; de)".
The urls the agent tries to access look like /rom/buecher/+B%C3%BCcher+rss+OR+rdf+OR+atom+OR+newsfeed+OR+weblog+OR+blog&hl=de", which aren't listed within the body or the head.
Does anyone know why?
Hm, this looks like a result from the Newsfeed Searchengine in RSSOwl. When results are coming for a search, RSSOwl is checking if the result points to a valid newsfeed, and in case a 404 is returned, does not show the result.
This is because, the search is based on a searchengine, which may not return newsfeeds in any case.
Is this behaviour somehow a problem for your domain, or where you just curious how so much 404 where produced from RSSOwl?
I don't think it is a problem.
I noticed it only because the 404 page is configured to inform me via email if a 404 happens (of course with a definition of exceptions).
I was just wondering why they occur.
Hm, in that case someone was searching for "Bcher" (books) in RSSOwl's feed searchengine. The searchengine returned your page as result, tried to parse it as feed, and got a 404. This maybe, because the searchengine was listing that URL once, but was not updating it to a new URL or removed it.
How often is this 404 happening a day?
