Send cookies over HTTPURLConnection

I am trying use the HTTPURLConnection class to open connection to a JSP and receive a response from a servlet. A response header is set in the JSP that need to be read in the servlet.

The code sample is as below

String strURL = "http://<host>:<port>/<context>/mypage.jsp";
String sCookies = getCookie();//method to get the authentication cookie(**SSOAUTH**) and its value for the current logged in user

URL url = new URL(strURL);
HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection();
urlConnection.setRequestProperty("Cookie", URLEncoder.encode(sCookies, "UTF-8"));
urlConnection.setRequestMethod("POST");
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);

DataOutputStream out = new DataOutputStream(urlConnection.getOutputStream());
out.writeBytes("lang=en");
out.flush();
out.close();

 //reading the response received from JSP and retrieve header value
response.write(urlConnection.getHeaderField("commAuth") + "<br />");

The issue is the passed SSOAUTH cookie is not sent to the JSP. If I send the UID/PWD instead of cookie as below the authentication succeeds and response is sent correctly.

urlConnection.setRequestProperty("username", "testuser");
urlConnection.setRequestProperty("password", "testpwd");

Is this the right way of sending cookie over HTTPURLConnection? or are there other parameters that need to be set?

You may want to try removing the URLEncoder.encode from the entire sCookies String. The cookie format should be in the form of NAME=VALUE, but by URLEncoding the whole string you will escape the =.
