Hi, Tag members,

I found the common practice of web server is to ignore the unknown query 
parameter.

For instance,

http://www.w3.org/?foo=bar

response the same as

http://www.w3.org

But should it be a 404 instead?

I think if this behavior is not specified, it will have serious 
consequence because one resource can in fact be identified by many 
URIs.  Should a recommendation be made, or there is already one that I 
am not aware of, regarding the response to unknown query parameter?
