Today I learned how to enable SPDY on my webserver. Starting from https://www.mare-system.de/guide-to-nginx-ssl-spdy-hsts/ it looks like this is a trivial change once ssl is correctly configured (something I managed to do a while ago).

However, I found that the nginx version in Wheezy is too old to support spdy. Some searching on the web finds dotdeb which has up-to-date versions. So

• Enable dotdeb as per instruction,
• upgrade the nginx-full package,
• change the site configuration from listen 443 ssl; to listen 443 ssl spdy;,
• finally reload the nginx configuration: sudo service nginx reload

And it is all there: http://spdycheck.org/#blog.hdurer.net
