Custom page session not working

Question

Hi All,
I have modified custom.jsp file to customize BI launchpad, where in this page I put code to display logon form and after form submission it will go to Action.jsp to validate credentials using below code.
// If no session already exists, logon using the specified parameters.
if (enterpriseSession == null)
  try
  // Log on to BusinessObjects Enterprise
  enterpriseSession = CrystalEnterprise.getSessionMgr().logon(strUserName,strPassword, "XXX:6400" ,strAuthType );
  defaultLogonToken = enterpriseSession.getLogonTokenMgr().getDefaultToken();
  enterpriseSession = CrystalEnterprise.getSessionMgr().logonWithToken(defaultLogonToken);
  // Store the IEnterpriseSession object in the session.
  session.setAttribute("EnterpriseSession", enterpriseSession);
  // Create the IInfoStore object.
  IInfoStore iStore = (IInfoStore) enterpriseSession.getService("InfoStore");
  // Store the IInfoStore object in the session using the
  // helper functions.
  session.setAttribute("InfoStore", iStore);
  // Store the logon token for later use.
  session.setAttribute("token", defaultLogonToken);
  catch (SDKException e) {  sSuccessFailMsg = e.getMessage();
This code is working fine and I am able to logon and go to home page, below is the issue I am facing can you please let me know how to solve this issue.
Once I logon to BI launchpad, if I refresh web page it's redirecting me to logon page again and also in next tab if I use same URL it's asking to to enter logon details.
Please lt me know how to use defaultlogon token to login without entering credentials.
Thanks,
Mani

Hello All,
I am able to resolve above issue by checking BO session in Custom.jsp. I think this  will be helpful for someone who is trying to do customization.
IEnterpriseSession enterpriseSession =(IEnterpriseSession)session.getAttribute("EnterpriseSession");
if (enterpriseSession != null)
String defaultLogonToken= (String)session.getAttribute("token");
response.sendRedirect ("/BOE/BI/logon/start.do?ivsLogonToken=" + defaultLogonToken);
Thanks,
Mani
