I'm wanting to make a site as fast as possible and as part of that will be using multiple sub-domains to essentially grow the number of concurrent connections in a browser.
My question is this: how can I avoid having to do SSL negotiation for each sub-domain? If I use a wildcard certificate (or SAN) can/will the SSL session established with the primary
www. domain be reused for the sub-domains to avoid the added latency of renegotiating the SSL connection?
The entire site will be behind SSL and it will have 2-3 additional sub-domains like
static. etc. Using NGINX.
