Subject: [Rails] Small regular expression question


I''m looking to write a regular expression that will match valid URLs.
My problem is that it almost works, except it accepts URLs with / in the middle
of them, suchs as:
http://www.ruby/rails.com

It looks (to me) like my regular expression should not match strings like that,
but it does.  Here is the regular expression:

.match(/^((http|https):\/\/)?[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.(\w+).*$/ix)

How can I make it not accept URLs with / in the middle of them?
