up.network up.network.shouldReduceRequests()

JavaScript function

Returns whether optional requests should be avoided where possible.

We assume the user wants to avoid requests if either of following applies:

• The user has enabled data saving in their browser ("Lite Mode" in Chrome for Android).
• The connection's effective round-trip time is longer than up.network.config.badRTT.
• The connection's effective bandwidth estimate is less than up.network.config.badDownlink.

By default Unpoly will disable preloading and polling if requests should be avoided.
