SPDY is an experimental protocol for multiplexing multiple, concurrent streams (typically HTTP request/response streams) over a single TCP connection.
Secure Sockets Layer (SSL) is a cryptographic protocol that provides secure communications over the Internet
"If we assume that you live in a poor coverage area and your phone and your tower are constantly dropping the signal then re-establishing a spdy connection is no worse off than re-establishing a tcp connection modulo ssl handshake"
from question "SPDY in context of mobile networks"
"Plus once spdy becomes more common ssl slow down won t really account for anything much"
"I m using keep-alive so i think the ssl handshake is more or less totally out but i hope to move to spdy soon so i don t really know how that helps after the initial handshake"
from question "Lowest possible expected HTTPS latency?"
