Most browsers, though, don't care if it's in the URL of a link. It's different, though, if you send this URL in an HTTP header. Older browsers like Netscape 4.x might refuse to process the URL if it contains invalid characters.

You're absolutely right, "?" is only good once, to separate the URL from the param string. And, of course, I forgot all about the very obvious "=" and all the others you mention.
