Java: get all the cookies from http response header

Share at Facebook

If you are using URLConnection class from java, then below code will be helpful for you to extract the Set-Cookie header values from the HTTP response. The below function just return you the cookies from,

public String getCookies() throws Exception{
String headerName = null, returnCookie = "";

// creeating the url connection object
URL url = new URL("");
URLConnection urlConnection = url.openConnection();

// checking for each headers
for (int i=1; (headerName = urlConnection.getHeaderFieldKey(i))!=null; i++) {
// if its set-cookie, then take it
if (headerName.equalsIgnoreCase("Set-Cookie")) {
String cookie = urlConnection.getHeaderField(i);
returnCookie += cookie + "\n";
return returnCookie;

Actually this function will help you to find other HTTP headers. you'll just need to replace the Set-Cookie with your header. It can be content encoding, Location, etc.
