It's the NetAccessor; libWWW, WinSock and Socket only test for XMLUrl::HTTP 
as protocol:

BinInputStream* WinSockNetAccessor::makeNew(const XMLURL&  urlSource, const 
XMLNetHTTPInfo* httpInfo /*=0*/)
{
     XMLURL::Protocols  protocol = urlSource.getProtocol();
     switch(protocol)
     {
         case XMLURL::HTTP:
         {
             BinHTTPURLInputStream* retStrm =
                 new (urlSource.getMemoryManager()) 
BinHTTPURLInputStream(urlSource, httpInfo);
             return retStrm;
             break;
         }

         //
         // These are the only protocols we support now. So throw and
         // unsupported protocol exception for the others.
         //
         default :
             ThrowXMLwithMemMgr(MalformedURLException, 
XMLExcepts::URL_UnsupportedProto, urlSource.getMemoryManager());
             break;
     }
     return 0;
}

The Mac-specific ones instead don't do this test and simply pass the URL to 
the OS APIs.
There is already a bug that I would like to tackle soon, that asks for a 
WinInet-based NetAccessor for Windows that would support a lot more 
protocols, including http, https, ftp. The downside is that WinInet is 
considered a desktop technology, not really suitable for creating services; 
a better API would be WinHTTP.

BTW, what is libcurl?

+1. I use it extensively.

libcurl is the library that underlies the ubiquitous curl command line 
tool commonly used on unixes but which compiles on other platforms as 
well, including Windows.

curl (http://curl.haxx.se/) supports all kinds of protocols, and is 
distributed under a very liberal free software license that doesn't put 
any restrictions on use, apart from maintaining their copyright.

I think libcurl would make a great netaccessor base, at least for 
unixes and Mac OX X, where libcurl is apt to be present anyway. It 
might make sense for Windows, through we'd then has an external 
dependency to resolve.
