Actually, I've read carefully this part of the manual before creating this topic. I still think the quoted passage explains nothing about virtualhost handling. It doesn't explain that skipping address or port will result in what I prefer to call "less prioritized vhosts". May be it's obvious from the parts you and Igor pointed at, but not to me, sorry.

I undrestood the concept (at least I think I did), so no further questions left - thanks. I think you don't indend to discuss how to write the documantation. :)
