How can I get POST variable form HTTP header with java? -

 socket client = ss.accept();                        bufferedreader in = new bufferedreader(new inputstreamreader(client.getinputstream()));             printwriter out = new printwriter(client.getoutputstream());             out.print("http/1.1 200 \r\n");              out.print("content-type: text/html\r\n");             out.print("\r\n");               out.print("<form method='post' action=''>first name: <input type='text' name='firstname' value='mickey'><br><input type='submit' value='submit'></form>"                     + "\r\n");              string line;              while ((line = in.readline()) != null){                 if(line.length() == 0) {                     break;                 }                      system.out.println(line);             }             system.out.println("lõpp");             out.close();             in.close();             client.close(); 

this code gives me after pressing submit.
