 // 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:
 //
 //   http://mathiasbynens.be/demo/url-regex
 //
 // 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)
 //
 // - Made starting path slash optional (http://example.com?foo=bar)
 // - Allow a dot (.) at the end of hostnames (http://example.com.)
 // - Allow an underscore (_) character in host/domain names
 // - Check dot delimited parts length and total length
 // - Made protocol optional, allowed short syntax //
 //
 // local changes:
 //
 // - removed "short syntax //", either http://, https://, ftp:// or just the domain
 //
 // Compressed one-line versions:
 //
 // Javascript regex version
