Version of of this class had some bugs so I corrected them and here is the latest version 🙂
Enjoy!

/**
* HTTP Request class
*
* You can use this class and distribute it as long as you give proper credit
* and place and leave this notice intact :). Check my blog for updated
* version(s) of this class (http://moazzam-khan.com)
*
* Usage Examples:
*
* Get Request
* --------------------------------
* HttpData data = HttpRequest.get("http://example.com/index.php?user=hello");
* System.out.println(data.content);
*
* Post Request
* --------------------------------
* HttpData data = HttpRequest.post("http://xyz.com", "var1=val&var2=val2");
* System.out.println(data.content);
* Enumeration keys = dat.cookies.keys(); // cookies
* while (keys.hasMoreElements()) {
* System.out.println(keys.nextElement() + " = " +
* data.cookies.get(keys.nextElement() + "rn");
* }
* Enumeration keys = dat.headers.keys(); // headers
* while (keys.hasMoreElements()) {
* System.out.println(keys.nextElement() + " = " +
* data.headers.get(keys.nextElement() + "rn");
* }
*
* Upload a file
* --------------------------------
* ArrayList files = new ArrayList();
* files.add(new File("/etc/someFile"));
* files.add(new File("/home/user/anotherFile"));
*
* Hashtable ht = new Hashtable();
* ht.put("var1", "val1");
*
* HttpData data = HttpRequest.post("http://xyz.com", ht, files);
* System.out.println(data.content);

You will also need the class below:
package moz.http;
import java.util.Hashtable;
public class HttpData {
public String content;
public Hashtable cookies = new Hashtable();
public Hashtable headers = new Hashtable();
}
