    Hello,

    Following the thread at https://wordpress.org/support/topic/can-page-caching-work-across-load-balanced-servers/

    We have the same problem: we have 2 backends, each with its own Redis. We need to replicate the cache purges on each backend.

    Does this issue have some update as of today ?

    If not, you talked about “creating a custom plugin that will call the cache purge across all servers once the purge is called”. I think we can do that, how would you start ? How to catch the purge orders efficiently ?

    Thank you very much !

    Hello @vmarko,

    Thank you for your kind proposal.

    For now, we have setup a cronjob which makes a Redis FLUSHALL on each backend, based on the last post_date/post_modified fields. This is of course not desirable in the long term as it impacts the frontend performance for a few minutes at each flush.

    I’d be so excited to consider a proper solution !

    Hello @snowraph

    Sorry for the late reply.

    I’ve suggested this to the team, and this is in the roadmap for the future, however, not something that can be done soon.
    We appreciate your patience and thank you for your suggestion.
