I want to grab from a https site which has the following:

<https://www.example.com/u/[username]/myPage>
<https://www.example.com/user/[username]/myPage>
<https://www.example.com/u/[username]/thoughts/2014AprilThoughs>
<https://www.example.com/user/[username]/thoughts/2014AprilThoughts>

/u/ is the same as /user/ and all pages on the site have no extensions like
the examples given above, how can I grab this kind? thank you!
