Need Javascript to create a file on the web server.

I am working for a call center company, and we have implemented a new web server (Microsoft web server 2008) in our company. The purpose of this server is to move all e-learning courses on the server and share the link with agents.

Earlier, I used javascript below to create a file (TXT and XlS) locally:

var fso = new ActiveXObject("Scripting.FileSystemObject");
var s = fso.OpenTextFile("\\Test.txt", 8, true, 0);
var player = GetPlayer();
var name = player.GetVar("TextEntry");
var email = player.GetVar("TextEntry1");
s.Write(" " + email);
s.WriteLine(" " + name);
s.WriteLine("==========");
s.Close();

However, I cannot use the same code anymore as all my courses hosted on a web server. I am looking for a javascript that performs the same function but this time, it creates a file on the web server.
