wget: Relative Links

 
 4.4 Relative Links
 ==================
 
 When ‘-L’ is turned on, only the relative links are ever followed.
 Relative links are here defined those that do not refer to the web
 server root.  For example, these links are relative:
 
      <a href="foo.gif">
      <a href="foo/bar.gif">
      <a href="../foo/bar.gif">
 
    These links are not relative:
 
      <a href="/foo.gif">
      <a href="/foo/bar.gif">
      <a href="http://www.example.com/foo/bar.gif">
 
    Using this option guarantees that recursive retrieval will not span
 hosts, even without ‘-H’.  In simple cases it also allows downloads to
 “just work” without having to convert links.
 
    This option is probably not very useful and might be removed in a
 future release.
