Header('location:... syntax help

when using header with location:, the paremeters for location that I can tell are

–header(‘location: /’); = got to root directory index page
–header(‘location: .’); = got to this directory index page
–header(‘location: /newdir/’); = got to //server/newdir directory index page
–header(‘location: /?getvar’); = got to root directory index page with $_GET = getvar
–header(‘location: http://www.sitepoint.com’); = got to sitepoint page

Are there others? I can’t find any documentation on this. Thanks

See http://en.wikipedia.org/wiki/HTTP_location and reference links on that page.
