I know this issue is very old news, but frankly I don't know of any thorough discussions or references. (Help!) In short, it would be great to hear the criteria HNers follow when choosing a link style. For example, from "http://example.com/d1/d2/doc.html" to "http://example.com/d1/foo.html" three choices come to mind:
1) Absolute URL ("http://example.com/d1/foo.html")
2) Relative URL, absolute path ("/d1/foo.html")
3) Relative URL, relative path ("../foo.html")
Which type of URL do you favor for your intra-site links? Why? Do you try as much as possible to use a single style throughout the site?
Further comments and references would be most welcome.
Cheers!
