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
