If all that's needed is a bool, does it make sense to define a new DNS 
record type for this sort of thing? It seems like a pretty near-perfect 
fit to me. It can be prefetched at DNS resolution time, so that all 
connections to the host are optimized, and you don't have to make a 
transaction (and parse the HTML) to then realize that other connections 
to the site can be optimized. It eliminates the potential minefield of 
different pages pointing to different hint files, and caching semantics 
could be maintained either at the HTTP request level or by putting 
something in the DNS record value. It shouldn't be that hard to deploy 
either.
