/ is a forward slash, not a back slash.
I would include the forward slash. If you type in "http://example.com"', your browser issues a request for "/" on the server at "example.com", which is exactly what it does if you type in "http://example.com/". In fact, my browser (firefox) automatically adds the slash to the url bar if I type a domain without it.
