OK. I need to find a way to clearly mark some of those tests as  
optional. Or maybe drop them altogether.

Interesting. http://search.cpan.org/~gaas/libwww-perl-5.808/lib/HTTP/Response.pm#$r-%3Ebase 
  is indeed all we need. Pity it doesn't record which source has been  
used as authoritative.

I guess base href and content-location are not so frequently used that  
we'd want to make our code mort complicated for it. I'd support using   
$response->base() if you think it makes sense.

My understanding is that the base URI should be taken as is, not  
necessarily as a directory. So your interpretation appears to be  
correct. However, it's fairly well known that desktop browsers are  
broken wrt Content-Location, so I wouldn't be surprised if they were  
broken for base URI calculation, too.

See e.g: http://www.nabble.com/Content-Location-as-Base-URI-td14247512.html
