Description not detailed enough. It should be clarified that www is the only subdomain and http(s):// the only protocol being tested against.

Current solutions will not work reliably for most real-world URL's.

Here are some url-patterns that should also be tested:

• https://dev.google.com/
• https://sub.dev.google.com/
• smb://sub.dev.google.co.en/?someParameter=value
• ftp://sub.dev.google.co.en:21/?someParameter=value
