A task to handle URI

Write a function, checkURIs(uri1, uri2) that can check if 2 URIs are equivalent. The function should return true if match, and false otherwise

Constraints and assumptions are as follow:

A port that is empty, or not given, is equivalent to the default port of 80

Comparisons of scheme names must be case-insensitive

Comparisons of host names must case-insensitive

Comparisons of path, hash, and querystring must be case-sensitive

Paths may contain traversal tokens . (same dir) and .. (one dir up) which must be accounted for

Characters are equivalent to their % HEX HEX encodings. (Other than typical reserved characters in urls like , / ? : @ & = + $ #)

Query string parameters must be equivalent in arbitrary order, BUT query string arguments of the same name must be listed in the same order in both URIs to be equivalent. There may be multiple (not just 2) args of the same name that need to be accounted for.

In-URI basic auth may be present: e.g. http://uname:passwd@host.com/foo/bar.html, auth must be case-sensitive

example:

checkURIs('http://abc.com:80/~smith/home.html',
  'http://ABC.com/%7Esmith/home.html'); // true
checkURIs('http://abc.com/drill/down/foo.html',
  'http://abc.com/drill/further/../down/./foo.html'); // true
checkURIs('http://abc.com/foo.html?a=1&b=2',
  'http://abc.com/foo.html?b=2&a=1'); // true
checkURIs('http://abc.com/foo.html?a=1&b=2&a=3',
  'http://abc.com/foo.html?a=3&a=1&b=2'); // false
