msapplication-config

Legacy Internet Explorer metadata that points to browserconfig.xml for Windows pinned-site tiles. Modern Chromium-based Edge does not use it.

Code examples

Good example
<meta name="msapplication-config" content="/browserconfig.xml">
Points to the configuration file at the site root.
Good example
<meta name="msapplication-config" content="none">
Disables automatic browserconfig.xml discovery in supporting legacy browsers.
Avoid this example
<meta name="msapplication-config" content="">
An empty value neither points to a file nor disables discovery.

Recommendations

  • 01
    Treat It as Legacy
    Keep this only when you still support Internet Explorer pinned sites. Use a web app manifest for current install metadata.
  • 02
    Use none to stop discovery
    Internet Explorer checks /browserconfig.xml by default. Set this property to none when you want to stop that lookup.
