Host Header Required

Hi 

I try to validate a wml document.

And I get the error

Line 2, column 93: 

         ... 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
                                                               ^

       Error: could not get "/DTD/wml_1.1.xml" from "www.wapforum.org"
(reason given was "Host Header Required")

it seems that the validator is missing
a 
Host: www.wapforum.org

in the request header.
