     String headerValue = "FAIL";                                                             
     int i = 0;                                                                               
     do {                                                                                     
         String headerName = wsConnection.getHeaderFieldKey(i);                               
         if (headerName != null && headerName.equals("Set-Cookie")) {                         
             headerValue = wsConnection.getHeaderField(i);                                    
             break;                                                                           
         }                                                                                    
         i++;                                                                                 
     } while (true);                                                                          
     return headerValue;                                                                      
 }                                                                                            
                                                                                              
 private static void setSessionIdFromCookie(String sessionString) {                           
     int jsessionIdx = 0;                                                                     
     jsessionIdx = sessionString.indexOf("jsessionid=");                                      
     if (jsessionIdx >= 0) {                                                                  
         sessionString = sessionString.substring(jsessionIdx);                                
         setSessionId(sessionString.substring(11, sessionString.indexOf(";")));               
     }
