Loading modules from a webserver

I have my own nodejs webserver and want to load my modules from this server. When I enter the following code on the right side of the Web IDE everything works hwever I get error messages like "Unexpected reserved word in http://192.168.88.117:8081/Wireless.js":­

Transmit = require("http://192.168.88.117:8081/tran­smitClass.js");
Wireless = require("http://192.168.88.117:8081/Wire­less.js");
Switch = require("http://192.168.88.117:8081/swit­chClass.js");

oWl = new Wireless('myAp', '192.168.88.117', new Switch());
oWl.init();

when I enter the command on the left side, the file is not found:

Transmit = require("http://192.168.88.117:8081/tran­smitClass.js")
Uncaught Error: Module http://192.168.88.117:8081/transmitClass­.js not found
 at line 1 col 65
....117:8081/transmitClass.js")

The same happens, when I require such a module within the module:

  doTransmit() {
    console.log('Call Transmit');
    var url = 'http://'+this.wServer+':8081/transmitCl­ass.js';
    Transmit = require(url);
    this.oTr = new Transmit(this.wServer, this.mThing);
    this.oTr.init();
  }

I do not understand this behaviour. Could somebody explain this to me?

Thanks for all,
Thomas
