follow-up re handling redirects with cookies and other stuff

After looking at the code further, I see that cookies are handled
in internal redirects if a cookie jar is associated with the
user agent object.  Perhaps a note should be added to LWP::UserAgent
saying something along the lines of:

   Redirect responses may include cookies, which will be lost if
   the redirection is handled internally and no cookie jar
   has been associated with the object.

Also, the following code 

$url = url '../../images/interface_images/logo.gif', 'http://www.ahn.com/';
$url = $url->abs;
print "$url\n";

produces:

  http://www.ahn.com/../../images/interface_images/logo.gif
  
Is that the correct behavior?  It seems like it should realize it's
impossible, and produce:

  http://www.ahn.com/images/interface_images/logo.gif

which is apparently what Netscape thinks it is.  Or is Netscape broken?

Finally, I noticed that HTML::LinkExtor doesn't find URLs in 
META tags (such as refresh).  From reading the HTML 4.0 spec,
it looks like there's no official specification for the attribute
syntax (yet?) ... it says it's specified by 'profiles' and
'This specification does not define formats for profiles'.
Anyway, I'm wondering if the development of something like
HTML::Meta would be useful, which could understand the profile
format and correctly parse meta tags?  Is anyone working on this?

Thanks,
