Sending binary file with socket

[grg79]

Hi!

I have already read all the forum posts related to this topic ... but unfortunately I can't upload a binary file through socket (js for indesign CC2017, os 10.13.3). 
The answer of server is always 400 Bad Request

I enclose the code ... 

Where I'm wrong?

Thanks!

sendDataToServerLocal("~/Desktop/prova.pdf", "prova")
function sendDataToServerLocal(filepath, filename) {
    conn = new Socket;
    reply = "";
    // Read file
    var f = File(filepath);
    f.encoding = 'BINARY';
    f.open("r");
    var fContent = f.read();
    f.close();
    // Connect to server
    if (conn.open("192.168.1.125:80", "BINARY")) {
        conn.timeout = 20000;
        boundary = Math.random().toString().substr(2);
        content = "--" + boundary
         + "Content-Disposition: form-data; name=\"file\"; filename=\"" + filename + ".pdf\"\r\n"
         + "Content-Type: application/octet-stream\r\n"
         + "\r\n"
         + fContent;
        cs = "POST mb_riediting2/php/upload.php HTTP/1.0\r\n"
         + "Content-Length: " + content.length + "\r\n"
         + "Content-Type: multipart/form-data; charset=utf-8; boundary=" + boundary + "\r\n"
         + "Host: 192.168.1.125:80\r\n"
         + "User-Agent: Apache-HttpClient/4.3.1 (java 1.5)\r\n"
         + "Accept: */*\r\n"
         + "Expect: 100-continue\r\n"
         + "\r\n"
         + content
         + "--" + boundary + "--\r\n"
        conn.write(cs);
        reply = conn.read(999999);
        conn.close();
  alert(reply)        
        if (reply.indexOf("200 OK") > 0) {
            alert("File successfully uploaded!");
        } else {
            //throw new Error("Error:" + reply);
        }
    } else {
       // throw new Error("Can't connect to server");
    }
}

Wouldn't that be stronger to use cURL ?

Have you find a way to do finally ?
