[users@httpd] Full cache locking requested

[Dirk Griffioen <di...@unified-streaming.com>]

Hi,

In the Apache docs here: 

https://httpd.apache.org/docs/2.4/mod/mod_cache.html#thunderingherd 

it says: 'When a cached entry becomes stale'

It seems that this does not include the first call: the first uncached fragment is not protected by the cache lock, so all requests for the first fragment will hit the origin.

In the case of live video streaming players keep requesting the last (new) fragment as it is produced by an encoder.

Unfortunately, other caching tools (Nginx, Varnish) must be used as Apache itself cannot be used.

Is ‘full cache llocking’ something that has been discussed or could be added?

Kind regards,

Dirk
