I stand corrected on HEXDIG case-sensitivity. Thanks everyone. Sorry to take up bandwidth on it. One other issue that I ran across in URI processing is that the grammar allows an absolute-URI to have an empty path (empty hier-part), meaning that http: and http:?x are acceptable absolute-URIs. absolute-URI = scheme ":" ( hier-part / opaque-part ) hier-part = [ net-path / abs-path ] [ "?" query ] Possibly these forms could be useful as some form of relative URI, but I don't see them as absolute URIs. Even as relative URIs, they seem dubious. On Wednesday 07 May 2003 9:51 am, Chris Newman wrote: > I concur with Paul's interpretation.
