Indeed. The spec specifies that relative/partial urls will work, and
the valid forms. (You can do "./" rather than having to use "index.html"
or other uglyness, for example).

Servers do indeed drop '..' parts so that someone can't try
and reference a document outside the 'document tree'. That's only wise.

A browser not implementing relative URLs is broken.
