Hi. I think it is pretty difficult to in Javascript do without the
ADODB.Stream class.

One possible solution (which is Internet Explorer specific and would
only be good for small files (up to 500k)) could be some rough manual
hack thus (untested):-

1. Use Scripting.FileSystemObject to get the file. I think it can
read binary into a string, but it ceases to be in binary format from
then on.

2. Convert the string to Base64 in Javascript(slow part).

3. Save the Base64 into a special XML node thus:-

var xml_dom = new ActiveXObject("MSXML2.DOMDocument");
xml_dom.loadXML('<?xml version="1.0" ?> <root/>');
xml_dom.documentElement.setAttribute("xmlns:dt",
"urn:schemas-microsoft-com:datatypes");
var l_node1 = xml_dom.createElement("file1");
l_node1.dataType = "bin.base64";
l_node1.nodeTypedValue=BASE_64_STRING_GOES_HERE;
xml_dom.documentElement.appendChild(l_node1);


4. Use the HTTPRequest object to send(xml_dom).

5. You will need some server side scripting to access from then on.
