How do I add cookies in a post request in Java?

Question

I was trying to get a certain page through java, but with this page I didn't succeed. Now in my browser it does work, but when I disable Cookies in the settings, it doesn't anymore.
So I probably need to add cookies to my post request in java.

So I went searching the interwebs, but unfortunately I couldn't really find anything useful. mostly it was vague, scattered or irrelevant.

So now my question :
Could anyone show me how to do it (mentioned above^^), or point me to a clear site?

Answer 1

Here's a simple example of setting a cookie in a POST request with URLConnection:

URL url = new URL("http://example.com/");
String postData = "foo bar baz";

URLConnection con = url.openConnection();
con.setDoOutput(true);
con.setRequestProperty("Cookie", "name=value");
con.setRequestProperty("Content-Type", "text/plain; charset=utf-8");
con.connect();

OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream(), "UTF-8");
out.write(postData);
out.close();

You probably need to pass a cookie from a previous request, see this answer for an example. Also consider using Apache HttpClient to make things easier.
