You will have to download/install the jetty implementation of npn jar yourself until it's merged into JDK7, don't know what are their plans. The APR seems faster - but not by a huge margin, I haven't tested the limits yet ( I want to find out what's the max number of kept-alive spdy connections - need more machines because of the 64k limit on local ports). > My question is this: will SPDY support be released in some form before > Tomcat 8 (in who's branch it seems to currently live)? JSR 340 (servlet > 3.1) seems to be targeting Q3 2012 and I would presume that that means > tomcat 8 is no sooner than Q3 or Q4 - 2012.

Then it's up to tomcat-dev on whether to backport the spdy packages, or have tomcat7 download the spdy jars separately ( i.e. release them as a 'plugin' / add-on ). It'll take a bit of time until it's done - not easy to find free time to work on this. Costin > > -Gus >
