How to print all the request headers which HttpURLConnection is sending?

Question

I am using HttpURLConnection in one of my Java program to hit a HTTP URL via Java.

I know I can set the request header value something like this.

connObj.setRequestProperty("User-Agent", "curl/7.29");

But I want to print all the request headers which is generated by URLConnection. Is that possible?

Answer 1

How about calling getRequestProperties() which as the documentation states

Returns an unmodifiable Map of general request properties for this connection.
