Enum ClientCachePreference

pub enum ClientCachePreference {
    Ignore,
    None,
    Changing,
    Full,
    MaxAge(Duration),
}

Automatically add cache-control header to response.

If a cache-control header is already present, it will be prioritized.

Variants

Ignore

Don’t manage the cache-control header.

None

Will not cache on client

Changing

A two-minute cache lifetime

Full

Will cache for 1 week

MaxAge(Duration)

Sets a max age for the content.

Note that this must be in seconds when sending a header. This will be rounded up.
