 Replying to [comment:6 jzlomek]:
 > It is better but still not correct. Consider this test:

 "a/b/../c/d/../e../.../..f/g../h../other/url/a.mp3/...");
 > It should give
 "http://server/foo/bar/a/c/e../.../..f/g../h../other/url/a.mp3/...".

 the components and for each ".." component remove the previous one (if
 there are some still).
