If the script download does not work using the normal process, a new service must be manually deployed to the customer’s SharePoint server. Configure the following keys to deploy this service manually:
Key name: "OptimizeKeyEnabled"
This service works only if you have a timeout issue and the key's value is true in the app config.
Key name: "OptimizeKeyBindingPath”
This key is used to set the service path to download information from the server.
Key name: "ForceOptimizeKeyTesting”
This key is used to ‘force download’ the script information from the server.
