Hi yaSSL users! See the following link for an explanation on SPDY: https://readwrite.com/2012/04/19/what-web-users-need-to-know-ab/
SPDY is a new protocol for web use proposed by Google and supported by many of the large web companies. It is based on HTTP, but it is faster and more suited to modern web usage.
You will note that SPDY mandates SSL, which will provide everyone more security in their day to day web use. We should also note that our friends at NGINX are supporting SPDY.
If you have comments or questions on running wolfSSL with SPDY, then please contact us at info@yassl.com.
