Results

URLMalformed

If you get this result then the string couldn't even be made into a url. It might contain spaces or other invalid characters.

URLNotAccepted

If you get this result then the string was made into a URL but no reply was recieved at that address

URLAccepted

If you get this result then the string was made into a URL and a reply was recieved from that address. A link with this result should be valid.
