I just was looking around too, and found roughly the same thing. However, it should be done with readyState 3, not with 4.... (as 4 is triggered when done)?

code:

---

86                // Called multiple while downloading in progress
87                case 3:
88                    // Notify user handler of download progress
89                    try {
90                        // Get the total content length
91                        // -useful to work out how much has been downloaded
92                        try {
93                            var contentLength = client.xmlhttp.getResponseHeader("Content-Length");
95                        } catch ( e) {
96                            var contentLength = NaN;
97                        } 
98     
99                        // Call the progress handler with what we've got
100                        client.userhandler.onProgress(
101                            client.xmlhttp.responseText,
102                            contentLength
103                        );
104     
105                    } catch ( e) { /* Handler method not defined */ }
106                break;

...

131        onProgress: function(responseText, length) {
132            echo("Downloaded "+responseText.length+" of "+length+"<br>");
133        },
