Nocache tags on 404 pages

[byron-roots]

We've been having some issues with our redis setup and it constantly reaching its memory limit. We've recently migrated a few sites over to the nocache DB driver.

Having a look at the table it seems to be excessively larger. One site has roughly 220,000 rows (863MB) whilst the next largest table is 27MB. I think this is due to nocache tags on our 404 pages, and then crawlers/bots landing on pages that don't exist.

I've removed the no cache tag regions from our 404 pages to try and prevent this, but is there a better way of handling this while having nocache tags? I also image pages with query strings are used for filtering content will be contributing to this as well where we can't really remove nocache tags.

Yes, you can enable the shared errors option. All 404s would be considered the same page, rather than a separate cached page for every missing page.

See the PR: #10294

In config/statamic/static_caching.php set 'share_errors' => true

This has not been documented yet though. statamic/docs#1376

Perfect, thanks!
