interesting enhancement to transport traffic in HTTP sessions proposed by Google is starting to gain popularity and traction. while i don’t use Chrome browser, in Firefox starting from version 11 you can turn the protocol on (
about:config -> network.http.spdy.enable=true). on the server side you should run mod_spdy if you’re running Apache server. it also makes sense to install Firefox extension signalling SPDY work. the end effect? SPDY gets the traffic faster (usually), as multiple sessions are initiated at the same time.
is it worth it? probably. i’m not happy that we’re not focusing more on SCTP that is readily available on multiple OSes. SCTP was build right from the start by networking guys (reference implementation was written by my friend at Cisco). SPDY is being developed by application guys, so their assumptions about TCP may need more scrutiny.
