Hi, I did a first round of backporting to tomcat7 - only the hooks. Please take a look and let me know:
https://github.com/costinm/tomcat/blob/trunk/tomcat7.diff I've also submitted to git the changes to support SPDY/NPN for NIO and JIO connectors - almost same diff, but the important change is: https://github.com/costinm/tomcat/commit/698f4105a818e872877f3e8d9c50e003e2e706f0 The problem is that it add a compile dep on http://wiki.eclipse.org/Jetty/Feature/NPN the classes are modified from openjdk7 - it'll also need to be added at runtime ( if spdy support with nio/jio is needed ), but I assume users can download the jar until it gets merged into jdk7. Alternative is to move all the coyote/spdy/{nio,jio} classes to a separate repository, outside tomcat tree. I guess we could also move all spdy impl to a separate repo and only leave the hooks.
