Cache enabling "OfflineHandler()" is getting executed before VB enter event in AppModule.js

Summary:

Hi I am implementing cache strategies in my Project. want to enable/disable this flag based on some external Variable Data, hence i had created a "VB-enter" event and from there I am setting flag value based on some condition for cache strategy. but when i executed this code the I found cache enabling code is even getting executed before VB Enter.

Since Offline Handeler is getting executed before VB enter event hence i am not able to set flag value "var flag=sessionStorage.getItem("SessionFlagName");".

Please help.

AppModule.prototype.vbEnter = function (arg1) {

  sessionStorage.setItem("SessionFlagName",arg1);

  console.log("vbEnter Line 133:"+sessionStorage.getItem("SessionFlagName"));
