HttpsUrlConnection and keep-alive

Question

I am using com.sun.net.httpserver.HttpsServer in my current project which deals with client-authentification etc.. Currently it only prints out the clients addr

Answer 1

try to add the following code:

con.setRequestProperty("Connection", "Keep-Alive");
con.setRequestProperty("Keep-Alive", "header");

Answer 2

We may setup an Apache Webserver, add following directives to see whether the Apache's access.log has a keep-alive connection for the http client.

LogFormat "%k %v %h %l %u %t \"%r\" %>s %b" common
CustomLog "logs/access.log" common 

http://httpd.apache.org/docs/current/mod/mod_log_config.html

"%k" Number of keepalive requests handled on this connection. Interesting if KeepAlive is being used, so that, for example, a '1' means the first keepalive request after the initial one, '2' the second, etc...; otherwise this is always 0 (indicating the initial request).
