up.protocol X-Up-Evict-Cache

HTTP header

The server may send this optional response header to control which previously cached responses should be evicted when this response is received.

The value of this header is a URL pattern matching responses that should be evicted.

For example, to evict all responses to URLs starting with /notes/:

X-Up-Evict-Cache: /notes/*

To evict all cache entries:

X-Up-Evict-Cache: *

To evict nothing, send false:

X-Up-Evict-Cache: false
