   I am using Ionic, so you'll have to adapt this if you are using plain 
cordova. I am also just using pseudocode here, but it should be clear:
   ```typescript
   class MyComponent {
     private iabSubscriptions = [];
     private iabObject: InAppBrowserObject|null = null;
   
     private subscribeIab(iab: InAppBrowserObject)
       // unsubscribe from the old IAB object
       for (const s of iabSubscriptions) {
         s.unsubscribe();
       }
       this.iabObject = iab;
       this.iabSubscriptions = [
         // do your subscriptions here
         iab.on('message').subscribe(arg => {
           const newIab = this.inAppBrowser.create(/* new url here */, 
'_system');
           this.subscribeIab(newIab);
         })
       ]; 
     }
   
     private openIab(url: string) {
       this.subscribeIab(this.inAppBrowser.create(url));
     }
   
     private closeIab() {
       if (this.iabObject) {
         this.iabObject.close();
         this.iabObject = null;
       }
     }
   }
   ```
