Forum: NGINX Advertise NPN without SPDY

Hello,

Is there a way for nginx to advertise the NPN extension without the use 
of
SPDY?

I'm asking because Chrome disables SSL False Start by default, unless 
the
NPN extension is advertised, and I don't want to use SPDY right now.


Thanks

I think you can do this fairly easily, mostly using nginx conf and
eventually 3rd party modules.

You could use headers_more[1] to always return the Alternate Protocol
headers.

Or this Lua snippet [2] (see ngx_lua module [3]), which will only
adverstise SPDY if a client is not already using it.

Happy hacking,
Matthieu.

You can't - NPN is advertised during SSL handshake.
