Prevent site directory from being displayed

I have a subdomain on which I have put up all the js code for my webiste to interact with another application. For eg: at code.example.com

Whenever, the user types this address,code.example.com, all the conte开发者_C百科nts of the directory are listed. How do I prevent this thing? I do not have nay index.html or index.aspx here.

In your IIS Configuration, turn off Directory browsing.

If you say what version of IIS you're using, then we can give specific steps on how to turn directory browsing off.
