Following my b9j.path release, I just finished up work on URI object-class for javascript.

It uses Steven Levithan's parseUri 1.2 to do the parsing.

Some example usage:

var uri = new b9j.uri.URI( "http://example.com/a/b?a=1&b=2&c=3&c=4&c=5" )
var host = uri.host()

var child = uri.child("c.html")            // http://example.com/a/b/c.html?a=1&b=2& ...
child.query().add({ c: [ 6, 7 ], d: 8 })   // ... ?a=1&b=2&c=3&c=4&c=5&c=6&c=7&d=8
child.query().set("b", 9)                  // ... ?a=1&b=9&c ...

return child.toString()

Again, while CPAN has URI.pm for URI-handling, JavaScript didn't really have an equivalent (parsing yes -- modifying/generating no).
