Re: GSoC Tomcat SPDY Connectors
There is an implementation of SPDY client and server on modules/tomcat-lite/java/org/apache/tomcat/lite/http/SpdyConnection - it's the previous version, didn't have time to update it - and I won't probably have until May, getting close to a launch. Note that at the moment SPDY can't be fully implemented in java - for this we'll need to use APR. The reason is that java SSL doesn't implement the 'next protocol negotiation' TLS extension - which is required by SPDY at the moment. Hopefully an alternative protocol negotiation will be allowed.

The last two days i was trying to figure out how connector development works. All I could find was a hint that there is a C and a Java part (I am very comfotable with Java and a little less with C). now my Questions: could somebody give me a hint: where i find the interface that connectors have to Implement? These are in the org.apache.coyote package. The Adapter is implemented by Tomcat, and the connector just gets an instance of it. where can i find the http connector sourcecode for reference? The implemented connectors are in sub packages under org.apache.coyote. how much of the work has to be done in C? Probably none. greetings Felix - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
