Is it possible to dump the HTTP Headers when using java.net.HttpURLConnection?

Question

I'm debugging some code that was written using java.net.HttpURLConnection. I'd like to set a property to enable logging of HTTP Request and Response headers as is possible in the Apache HTTP Components library with the org.apache.http.headers category.

Is this possible with HttpURLConnection? Do I need to breakout Charles Proxy or Wireshark?

According to Sun's HttpURLConnection source there is some logging support via JUL.

This would require setting up java.util.logging with sun.net.www.protocol.http.HttpURLConnection.level=ALL.

See http://www.rgagnon.com/javadetails/java-debug-HttpURLConnection-problem.html for example.

There is also system property -Djavax.net.debug=all. But it's mainly useful for SSL debugging.

BTW, Wireshark is also a rather easy option.

This gave me exactly what I needed. The source is always the source of truth so I should've looked there first but this seems like nice functionality that I'm not sure why it didn't make it to the Javadoc.
