java.lang.Object
- org.apache.coyote.spdy.SpdyAprNpnHandler

All Implemented Interfaces:

NpnHandler<Long>
```
public class SpdyAprNpnHandler
extends Object
implements NpnHandler<Long>
```
Plugin for APR connector providing SPDY support via NPN negotiation. Example: <Connector port="9443" npnHandler="org.apache.coyote.spdy.SpdyAprNpnHandler" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" sslProtocol="TLS" SSLCertificateFile="conf/localhost-cert.pem" SSLCertificateKeyFile="conf/localhost-key.pem"/> This requires APR library ( libtcnative-1 ) to be present and compiled with a recent openssl or a openssl patched with npn support. Because we need to auto-detect SPDY and fallback to HTTP ( based on SSL next proto ) this is implemented in tomcat a special way: Http11AprProtocol will delegate to Spdy.process if spdy is negotiated by TLS.
