Url Scanner says 'google.com' is invalid url

[smartbos]

When I add 'http://google.com' to $urls array,
'http://google.com' is returned as a invalid url.

I tried some urls and the results were below
http://facebook.com (pass)
http://google.com (invalid)
http://naver.com (invalid)
http://github.com (invalid)

I tested it on localhost.

@smartbos For what it's worth. This isn't an issue in this scanner code. The options method is intended to see what type of communication options are allowed on a target, but Google is blocking all option requests.
