I'm using Tomcat 6.0.24 on Ubuntu (JDK 1.6) with an app that does Comet-style requests on an HTTPS connector (directly against Tomcat, not using APR).
I'd like to set the keep-alive to 5 minutes so I don't have to refresh my long-polling connections. Here is my config:
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="1000" keepAliveTimeout="330000" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" />
Unfortunately it seems that the server closes the connection after 65 seconds. The pcap from a sample session goes something like this:
T=0 Client sends SYN to server, handshake etc. T=65 Server sends FIN to client T=307 Client sends FIN to server
(I'm guessing the 5 minute timeout on the client is due to the HTTP lib not detecting the socket close on the server end, but in any case -- the server shouldn't be closing the connection that early)
(edit: this works as expected when using the standard HTTP connector)
