up.network up:network:late

DOM event

This event is emitted when AJAX requests are taking long to finish loading.

Slow server responses

Timing

By default, Unpoly will wait 400 ms for an AJAX request to finish before emitting up:network:late. You may configure this delay globally, for individual links, or for specific requests.

Once all responses have been received, an up:network:recover event will be emitted.

If additional requests are made while Unpoly is already busy waiting, no additional up:network:late events will be emitted.

Default behavior

By default, Unpoly will show a progress bar while late requests are pending. You can disable the progress bar or implement custom loading indicators.
