the regular expression composed & commented
could be easily tweaked for RFC compliance,
it was expressly modified to fit & satisfy
these test for an URL shortener:

Notes on possible differences from a standard/generic validation:

- utf-8 char class take in consideration the full Unicode range
- TLDs have been made mandatory so single names like "localhost" fails
- protocols have been restricted to ftp, http and https only as requested

Changes:

- IP address dotted notation validation, range: 1.0.0.0 - 223.255.255.255
  first and last IP address of each class is considered invalid
  (since they are broadcast/network addresses)

- Added exclusion of private, reserved and/or local networks ranges

- Made starting path slash optional (http://example.com?foo=bar)

- Allow a dot (.) at the end of hostnames (http://example.com.)
