Hello,

I just got a page like this: http://troels.arvin.dk/misc/wikipedia/200error/ copied from http://en.wikipedia.org/w/index.php?title=Comparison_of_Java_to_C_Plus_Plus&...

The HTTP response status code for that page was 200 (OK), according to my LiveHTTPHeaders Firefox-extension.

I suggest that such error pages be delivered with a 500 (internal error) response code. The problem with delivering error-pages using status 200, is that it may be cached by proxies and picked up by search engine bots.
