URI host?blah

[Mirar @ Pike developers forum]

If this is not possible, this kludge will fix the problem:

do_sync in Protocols/HTTP/Session.pike:

            while( con->status == 100 )
               con->ponder_answer( con->datapos );
            if (con->status>=300 && con->status<400 &&
                con->headers->location && follow_redirects)
            {
+              string a,b,c;
+              if (sscanf(con->headers->location,"%s://%s?%s",a,b,c)==3 &&
+                  search(b,"/")==-1)
+                 con->headers->location=a+"://"+b+"/?"+c;

               Standards.URI loc=
                  Standards.URI(con->headers->location,url_requested);

               if(loc->scheme=="http" || loc->scheme=="https")
