Thanks for the clarification.

When I read through the SPDY documents up to version 4 I saw no
mention of server hints at all. I thought I must have missed something
since every news or review article I read mentions SDPY hints, but no
one ever had an example.

BTW, SDPY on Nginx has worked flawlessly in a public beta production
environment for three(3) weeks now. We see an average of 739
concurrent ips connecting with one TCP connection each and asking for
21 objects per un-cached page request. This has reduced the load
(cpu/ram) on our FreeBSD stateful firewall by ~63% due to less states
and decreased client load times by 47%. I can happily report no
crashes, faults or page errors with the current source build. Thanks
for all the hard work.
