QuickStep commented on a Page, $furl() .is URL Identifier  -  Mar 01, 2006

test#test is a valid anchor (not 2 anchors, 1 anchor with # in it), it may be considered obsolette by some browsers, but EVEN firefox considers it as a valid anchor (just tested it).
So you are basically saying that whatever protocol is used, it is a valid url (http1://, httpmrc://, bla://) even though they don\'t exist and no browser can display them?
And I just noticed that you consider sites with the ~ in it NOT a valid url. I think you misunderstood http://www.ietf.org/rfc/rfc1738.txt, UNSAFE != INVALID. Here just visit this site as an example http://www.let.uu.nl/~ctl/ I\'m pretty sure that whatever browser you use, it will open the site. And surely the creators of your browser know better of what url is valid and what url is invalid.
