I'm developing a desktop SaaS app that relies heavily on local browser caching, using IndexedDB. This is to reduce server load. This is a part of the business strategy.I am making IndexedDB a requirement to use the app. IndexedDB is available on 97% of all browsers. If IndexedDB support is not found, I will show a popup.Is this reasonable? Do you thinks users would make a fuss? Are there any corporate policies that disable the local cache, or clear it when the browser closes?
