http://www.mywebsite.com/name11-name12-name13-name14-name15/11117657/ca

Options: ^ and $ match at line breaks

Match the characters “http://” literally «http://»
Match any single character that is not a line break character «.*»
   Between zero and unlimited times, as many times as possible, giving back as needed (greedy) «*»
Match the characters “mywebsite” literally «mywebsite»
Match the character “.” literally «\.»
Match the characters “com/” literally «com/»
Match the regular expression below and capture its match into backreference number 1 «(\w+(?:-(?!\d{4,})\w+)*)»
   Match a single character that is a “word character” (letters, digits, etc.) «\w+»
      Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
