Software Development in a Nutshell

• on web

Group Policies which could affect your Web Application

We are working on a web application which heavily depends on the following browsers’ features:

  • Application Cache - it allows websites to ask browser to cache them, so that users are able to open these websites offline.
  • Indexed DB - it allows websites to store data in the browser cache, so that all needed data will be available offline.
  • Web Storage - it allows websites to store settings in the browser cache.

Group Policy

It’s common for Enterprises to adjust default IE 11 settings using Group Policies. In such cases some of the functionality will not be available. For example website may fail to work offline if it’s unable to store data into browser’s cache. We prepared a list of the settings which might have impact on the websites utilizing above browser features.

    • Allow clearing browsing data on exit. Not Configured by default. If Enabled could cause a data loss, also users won’t be able to open application offline.
