Turn off Nginx SPDY?

I want to test non-SPDY vs SPDY performance for Nginx and I have Nginx
compiled with SPDY support and it’s enabled by adding to listen
directive
the spdy option as per
http://nginx.org/en/docs/http/ngx_http_spdy_module.html.

I thought that omitting the spdy option would disable SPDY temporarily ?
But
it seems spdycheck.org still reports the https:// site supports SPDY and
browser shows site with SPDY support even with the spdy line removed
from
listen directive ?

Or is only way to disable, is to recompile Nginx without SPDY support ?

cheers

Without the parameter on listen directive SPDY is disabled.

There are only three possibilities for this:

  1. You have not reloaded the configuration after it was changed, then
    nginx is working with the old one.

  2. You have removed parameter only from one listen directive but there
    is another one. It works per addr:port pair (like most of listen
    parameters), not per server block.

  3. Your browser and spdycheck.org is lying about current status.

I see i believe my problem is #2 as i have another vhost with spdy
enabled
on same addr:port pairing !

Thanks Valentin :slight_smile:
