Fetching a web page

[Eric Plaster]

 
I'm trying to pull down a web page and I'm having some problems...  I'm using the code below (loadWebPage()), and it never says that there is data available.  Am I doing this all wrong?  Keep in mind this is just to see if I can pull a page, I haven't cleaned it up or do anything other then just dump the contents...

-thanks for any help

BTW, this is code that I ripped out of postings n.p.m.netlib and nsXmlRpcClient and a few others.  So if it looks a little familiar... ;)
 

/* Get a pointer to a service indicated by the ContractID, with given interface */
function getService(contractId, intf) {
    return Components.classes[contractId].getService(Components.interfaces[intf]);
}

function loadWebPage() {
  // **** Set this to a small, valid file
  var url = "http://www.talkware.net/";

  // convert to nsIURL interface.
  var url_ob = Components.classes["@mozilla.org/network/standard-url;1"]
    .createInstance()
    .QueryInterface(Components.interfaces.nsIURL);
  url_ob.spec = url;

  // Now open the URL.
  var ioService = getService('@mozilla.org/network/io-service;1',
            'nsIIOService');
  var atomService = getService('@mozilla.org/atom-service;1',
            'nsIAtomService');

  var channel = ioService.newChannelFromURI(url_ob)
    .QueryInterface(Components.interfaces.nsIHTTPChannel);

  channel.SetRequestMethod(atomService.getAtom('GET'));
  channel.SetRequestHeader(atomService.getAtom('content-type'), 'text/html');

  var inputStream = channel.openInputStream();
  // make the input stream scriptable.
  var sinputStream =
    Components.classes["@mozilla.org/scriptableinputstream;1"]
    .createInstance()
    .QueryInterface(Components.interfaces.nsIScriptableInputStream);
  sinputStream.init(inputStream);

  while(!sinputStream.available()) {
    dump("waiting....\n");
  }
  while(sinputStream.available()) {
    dump("Read '" + sinputStream.read(1024) + "'\n");
  }

  // close everything I know how!
  inputStream.close();
  sinputStream.close();
}
