    copied!<p>I am trying to make a post request on this page <a href="http://www2.gcitrading.com/quotes/converter.asp" rel="nofollow">http://www2.gcitrading.com/quotes/converter.asp</a>, but its not working..I still get the same page after my post request (without the result).</p> <p>When I use the browser, after I click convert the page turns to <a href="http://www2.gcitrading.com/quotes/converter.asp?lang=" rel="nofollow">http://www2.gcitrading.com/quotes/converter.asp?lang=</a> Im really confused with this one. How can I make this work?</p> <p>Here is my code:</p> <pre><code>public static void main(String[] args) { Socket sock = new Socket(); InputStream in; OutputStream out; byte[] readBuffer = new byte[4096]; String res = ""; try { sock.connect(new InetSocketAddress("www2.gcitrading.com", 80)); in = sock.getInputStream(); out = sock.getOutputStream(); out.write(new String("GET /quotes/converter.asp HTTP/1.1\r\n").getBytes()); out.write(new String("Host: www2.gcitrading.com\r\n\r\n").getBytes()); while(true) { int readSize = in.read(readBuffer); if(readSize &lt; 1) break; res += new String(readBuffer, 0, readSize); if(res.contains("&lt;/html&gt;")) break; } String cookie = res.substring(res.indexOf("kie:") + 5,res.indexOf("path=/")+6); System.out.println("SHow cookie - " + cookie); String convert_this = URLEncoder.encode("form_amount=1&amp;form_from_currency=DZD&amp;form_to_currency=USD", "UTF-8"); out.write(new String("POST /quotes/converter.asp?lang= HTTP/1.1\r\n").getBytes()); out.write(new String("Host: www2.gcitrading.com\r\n").getBytes()); out.write(new String("Content-Length: " + convert_this.length() + "\r\n").getBytes()); out.write(new String("Content-Type: application/x-www-form-urlencoded\r\n").getBytes()); out.write(new String("Cookie: " + cookie +"\r\n").getBytes()); out.write(new String("\r\n").getBytes()); out.write(convert_this.getBytes()); readBuffer = new byte[4096]; res = ""; while(true) { int readSize = in.read(readBuffer); if(readSize &lt; 1) break; res += new String(readBuffer, 0, readSize); if(res.contains("&lt;/html&gt;")) break; } System.out.println(res); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } </code></pre> <p>Thanks. Btw, I need to achieve this using c/c++ sockets, but I tested it using java first.</p>
