I don't envision the PDA people implementing their browser that way, no
matter how strongly we attempt to tell them what to do in the HTTP spec.
More than likely they will put a "Failed to contact server, showing old page
from cache." message in the status bar and display the page as normal. I'd
guess they would willfully work outside the bounds of the HTTP spec before
they would severly hinder their application in that manner.
