RSS2-Feed is getting cached?

    Hi Marko,

    I hope you had a good week so far! On the bottom of my RSS-Feeds I find this:

    <!--
Performance optimized by W3 Total Cache. Learn more: https://www.boldgrid.com/w3-total-cache/

Object Caching 142/156 objects using disk
Page Caching using disk: enhanced (Page is feed) 
Lazy Loading (feed)
Database Caching using disk (Request-wide modification query)

Served from: domain.com @ 2022-09-15 15:39:36 by W3 Total Cache
-->

    I have two questions:

    1. For Page Cache I have the caching of Feeds unchecked. Is this still expected behavior?

    2. Is it recommended to cache feeds in general? It feels like this doesn’t help when it comes to having them as recent as possible or do I get that wrong? Should I check the caching for feeds in Page Cache / does it make a difference regarding above quoted appendix?

    Thanks and best regards,
    eC

    Hello @ecronik

    Thank you for reaching out and I am happy to assist you with this.
    When you have the following in the W3TC HTML snippet:
    Page Caching using disk: enhanced (Page is feed) it means that the feed is not being cached.
    The same goes if the page is excluded from the cache you would see something like:
    Page Caching using disk: enhanced (Requested URI is rejected)
    This reflects the fact that the option “Cache feeds: site, categories, tags, comments” is not enabled in the Page Cache section so to answer your first question, yes this is expected behavior when the option is unchecked. If the option was checked you would see the snipped without (Page is feed)

    As for your second question, although feeds don’t make much buzz as they used to do, they are still a part of a website infrastructure and are widely used by RSS readers and web crawlers. And it’s recommended to cache feeds to decrease the server load.

    In the Performance>Page Cache>Purge policy section, there are options that you can select in which case the cache will be purged, and as you can see, you can Specify the feed types to purge:
    So once the content is updated or a new article is added, the pages will be purged from the cache, and the feed also.

    I hope this helps!

    Thanks!

    Hmm, mine is being cached then, and even generating error in the php log:
