How can I improve this regex?

Question

I am trying to write regex to check domain and path after it for some context value path. I wrote this regex which works. Is there any simple version for this without using or?

  ^/(creditcards|creditcards/.*)?$

    To match:    
    /    
    /creditcards    
    /creditcards/something

Try this:

^/(creditcards(/.*)?)?$
