However, I don't think it is legal/valid to have a "+" character in an encoded URI.
However, when you type in your browser http://localhost:8080/foo+/bar+/, then (hunchentoot: request-uri *) returns "/foo+ /bar+/" (not"/foo%2B/bar%2B/" ). I specifically checked that mod_autoindex (Apache) in such cases is also not encode +.
