Problem with encodeRedirectURL

[Curtis Polk]

When I try this with cookies disabled, I get a 404 from either Netscape 4 or
IE 5, with this message:the requested URL /2.html;jsessionid=bx4wqcd1y1 was
not found on this server.  Isn't it supposed to append a question mark  to the
URL, then the session ID, and not a semicolon?
