Hence the header, even if its "0" today. That said, I'm torn on the "Beacon-Age: 0". On the one hand, saved bytes are good, but I do think it could make things a bit more difficult.. If some UA decides to skip the header (bug or otherwise), then as a developer I have to resort to UA detection (ugh) to winnow out valid vs. invalid cases. A guaranteed header makes things much easier. ig
