how to set an http request header used in HttpURLConnection ?

[maong]

Is it possible for a Java network application, using HttpURLConnection, to
set or influence the setting of, http headers like Connection. One example
might be setting Connection: Close to indicate that this is the last
expected transaction for a while and the persistent connection can be closed
with the response.

setRequestProperty will throw an Illegal State Exception - Already
connected. This is a persistent connection.
