Error while creating user for a domain

Question

i am developing a web-application which is hosted on tomcat server.
it is creating domains and users at another remote domain server.
localy it is working fine..
but when i test it online..
the problem is,
sometimes it works fine ,the domains are being creted at remote server..
but sometimes it delivers error that domain at remote server can not be created.
Is it due to fact that theat some errornous code in the buffer of application have older versions of applications causing the error ?
Code::
if(strPlanId.equalsIgnoreCase("3")) {
                //Create domain account  for planid=3 plantype=Cp
                blnOK=false;
passwordGS comes from database
strUrl="http://sosync.net/sosync/admin?pwd="+passwordGS+"&action=user_createdomain&domain="+strSubDomain+".gosync.net&adminpassword=aspire3002&diskquota="+longdk;  
                u=new URL(strUrl);
                uc=(HttpURLConnection)u.openConnection();
                code=uc.getResponseCode();
                if(code == 200) {
                    rUrl="/TransCompleteServlet";
                    blnOK=true;
                    uc.disconnect();
                } else {
                    rUrl="/GSView.jsp?page=GSError.jsp?REQ=Unknown";
                if(blnOK) {
                    String strUrlUser="http://gosyncdesk.net/gosync/admin?pwd="+passwordGS+"&action=user_createuser&username="+strEmailId+"&password="+strPassword+"&domain="+strSubDomain+".gosync.net&communityname=Default&firstname="+user.getFirstName()+"&lastname="+user.getLastName();
                   URL u1=new URL(strUrlUser);
                HttpURLConnection   uc1=(HttpURLConnection)u1.openConnection();
                    code=uc1.getResponseCode();
                    response1=uc1.getResponseMessage();
                    if(code == 200) {
                        rUrl="/TransCompleteServlet";
                        String strUrlTZ="http://gosyncdesk.net/gosync/admin?pwd="+passwordGS+"&action=user_setuserpreference&username="+strEmailId+"&domain="+strSubDomain+".gosync.net&name=web_timezone&value='"+timeZone+"'";
                        u=new URL(strUrlTZ);
                        uc=(HttpURLConnection)u.openConnection();
                        code=uc.getResponseCode();
                          if(code != 200) {
                           rUrl="/GSView.jsp?page=GSError.jsp?REQ=Unknown";
                    } else {
                        rUrl="/GSView.jsp?page=GSError.jsp?REQ=Unknown";
                        mailUtil.sendMail_admin("Error In Creating  User for the Domain","While creating domain for "+user.getEmail()+" user could not be created due to following reason: <BR> "+response1+"<br>GoSync UserName:"+strEmailId+"<br>GoSync Password:"+strPassword+"<br>GoSync Domain :"+strSubDomain+".gosync.net and URl String was :"+strUrlUser+"");
            }

Answer 1

if the problem is caching try setting the useChasses to false
uc.setUseCaches(false);
