up.network up.cache.alias(oldRequest, newRequest)
JavaScript function

This feature is experimental. It may be changed or removed in a future version.

Makes the cache assume that newRequest has the same response as the already cached oldRequest.

Unpoly uses this internally when the user redirects from /old to /new. In that case, both /old and /new will cache the same response from /new.


oldRequest Objectorup.Request

The earlier request or request options.

newRequest Objectorup.Requestorundefined

The new request or request options.

If oldRequest wasn't found in the cache, undefined is returned.
