phk says to remove the + :)

I tested it with the following VCL code:

sub vcl_fetch {
        set obj.http.X-Varnish-Hash = obj.hash;
        set obj.http.X-Varnish-Foo = req.url "#" req.http.host "#";
}

which gives

X-Varnish-Hash: /index.html#www.des.no#
X-Varnish-Foo: /index.html#www.des.no#

showing that the two are identical.

DES
