Hello,
is it possible to inspect http headers (like hostname/uri) and do backend
switching in tcp mode via spdy?
My config is something like:
...
frontend app
bind :443 ssl crt cert.pem npn spdy/3.1,http/1.1
tcp-request inspect-delay 5s
tcp-request content accept if HTTP
acl is_upload hdr_beg(host) -i upload
acl spdy ssl_fc_npn -i spdy/3.1
use_backend upload_spdy if is_upload spdy
use_backend upload if is_upload
use_backend www_spdy if spdy
default_backend www
...
In short - I want to use a single haproxy instance and switch backends based
on Layer 7 information while still providing spdy when possible.
If the client doesn't support spdy (like IE etc) the configuration works as
expected but for spdy-enabled clients everything falls back to default
backend.
I tried to experiment also with making the acl with 'req_ssl_sni' but it
doesn't work in case of spdy either (I wouldn't want to use the SNI approach
anyways since there are quite a lot of clients (like android 2.3.x/XP etc)
which don't support it).
Is it in any way possible (like different approach to deal with the spdy
protocol) or just better switch back to http mode and forget spdy?
