I needed to make a HTTP GET request with some additional header parameters from my JSP and I stumbled upon this solution JSP make http get request and get json response which solved most of my problem. I am able to make the HTTP call from inside the JSP but I am trying to add a couple of authentication fields to the request header for the URL and I am unable to figure out how to. 

<%@page import="java.io.*" %>
<%@page import="java.net.*" %>

<%
 String recv;
 String recvbuff;
 URL jsonpage = new URL("http://www.yoursite.com/jsonresponse");
 URLConnection urlcon = jsonpage.openConnection();
 BufferedReader buffread = new BufferedReader(new InputStreamReader(urlcon.getInputStream()));

 while ((recv = buffread.readLine()) != null)
 recvbuff += recv;
 buffread.close();

 System.out.println(recvbuff);
%>

I believe adding a RequestProperty is what you are looking for.

urlcon.addRequestProperty("key","value");

JavaDocs URLConnection
