Unwanted regular purges happening

We have a large website with thousands of pages. So we don’t want regular purges.

Every time I navigate in the admin portal, it seems to purge the cache. See debug log below

The only real peculiarity about the site is that it uses cloudfront as a CDN so there is an edge server and the admin is on the origin.

Just to clarify

1. just logging into the website wp-admin triggers a purge. Definitely has been working cos there were 5000+ posts purged. Any navigation in admin whatsoever triggers purge.
I looked at this page on your site, and I was not doing any of these activities to purge.

2. the cache is for the public cloudfront site, so has the ‘public’ url. The name of the wpo-cache directory where it stores it is the ‘public’ url. The admin installation uses an ‘origin’ url. This Cloudfront detail might be entirely irrelevant.

I found a solution, although it requires an edit on each plugin update.

The Cloudfront dual site url issue was the cause.

in cache/class-wpo-page-cache.php

there is a section that detects site changes
I commented out these lines:
```
          if ($is_the_site_url_or_folder_changed) {
                  $is_cache_purged = $this->purge();
                  if ($is_cache_purged) $this->file_log("Full Cache Purge triggered by: ". __METHOD__);
          }

          if (!$this->write_advanced_cache()) {
                  add_action('admin_notices', array($this, 'notice_advanced_cache_autoupdate_error'));
          } else {
                  $this->update_cache_config();
          }
```

Now the cache doesn’t get totally purged
But when a new story is posted, there’s no partial purge either.

Hi @nm001!
Please accept my apologies for the delayed response.

To help with investigating this, please check the advanced-cache.php file in the wp-content directory of your site files. Send us what you have in line 5 that starts with:
// WP-Optimize advanced-cache.php (written…

In the meantime, we will also run some checks on our end.

Regards.
