Just found this snippet stored away on one of my harddrives. Dated March 2003:

code:
/***********************\
 * Dynamic File Reader *
 * by: Liorean         *
\***********************/

function File(){
  var r;
  switch(0+(1*(typeof document.getElementById!='undefined')+2*(typeof clientInformation!='undefined')+4*(typeof netscape!='undefined'))*(typeof opera=='undefined')){
    case 3:
      r=new ActiveXObject('Microsoft.XMLHTTP');
      break;
    case 4:
      r=new NN4HttpRequest;
      break;
    case 5:
      r=new XMLHttpRequest;
      break;
    default:
      r={
        open:function(){},
        send:function(){return false},
        responseText:''
      };
      break
  }
  this.prototype=r;
  return r;
}

function NN4HttpRequest(){
  this.url=this.responseText=''
}
NN4HttpRequest.prototype.open=function(m,u){
  this.method=m||'GET';
  this.url=u
}
NN4HttpRequest.prototype.send=function(){
  if(this.url=='')return false;
  if(!/^[a-z]+:/.test(this.url))
    this.url=String(window.location).replace(/\/[^\/]*$/,'/'+this.url);
  var l,
    b;
  this.responseText='';
  b=new java.io.BufferedReader(new java.io.InputStreamReader(new java.net.URL(this.url).openStream()));
  while((l=b.readLine())!=null)
    this.responseText+=l+'\n';
    if(b!=null)
      b.close();
  return true
}

Seems you can teach old dogs new tricks after all

One of the first thing I made when I learnt PHP in 2000-2001 was some sort of chat client. It didn't use XHR but the good old 1px IFRAME technique with an open connection.

Well, I did some form of JavaScript Remote Scripting Back in nn4/ie4, but you had to jump through hoops and climb over cesspits to get it working there... and half the time the browser crashed if your file timed out...

Never really liked the iframe/layer method though.
