Hello. I manage a small blog network (17) that has a lot of traffic (20MM visits/month). I use Wordpress Multisite to manage it, each blog has its own domain name, and all are served from the same WP install. I’m thinking about implementing SPDY to speed up the sites, I know I need SSL certificates for this to work. 1. Will I need a certificate for each website? Or just one certificate for the main site to encrypt the connection and that’s it? 2. I have a single server directive holding most of the configuration stuff with ‘default\_server’, and then some individual settings for each site, mostly www-to-no-www redirects and legacy url rewrites. If I need a certificate for each website, do I need to replicate all the wordpress config for each domain, having a complete server directive with all WP + PHP stuff in it for each domain? Does this impact nginx’s performance in any way? This one’s just lazy: is the RPM package hosted in the nginx repo (for yum in Fedora/CentOS, etc) compiled with SPDY on or I’ll need to compile my own version? Thanks in advance. Cheers!

I don’t use SPDY, so take what I say as being from an SSL perspective, not a SPDY one. If your 17 blogs live under the same domain that you own, you could look at using a wildcard SSL cert. You’d only need a single IP/server{} combo for each wildcard cert, and a single wildcard cert for each unique domain suffix you own. If that’s not helpful, and the domains are all different, then you could look at a UCC (or SaN) SSL cert. This would also allow you to use a single IP/server{} block, but would probably be uneconomical if your domain list changes frequently. Finally, if you need/get a separate SSL cert for each domain, you will need a distinct IP and server{} block for each. 17 domains with SSL and a separate server{} for each will not affect performance, IME. You’ll just proxy\_pass to the same backend from each. ## HTH, Jonathan Jonathan M. // Oxford, London, UK > **[Jonathan Matthews :: Words Typed, Great Rates For Cash](https://www.jpluscplusm.com)** ---

regarding recompile question: SPDY is supported with OpenSSL 1.0.1 so if your distro using earlier version, SPDY will not be supported, you can check “nginx -V” if SPDY been enabled. When recompiling you can use openssl source package and link it statically to nginx if needed –with-http\_spdy\_module –with-openssl=/path/to/unpacked/source/openssl-1.0.1e Posted at Nginx Forum: > **[Re: SPDY certificates and Wordpress multisite](https://forum.nginx.org/read.php?2,239609,239611#msg-239611)** > > Hello.
