X-Cache miss

    I found that define(‘WP_CACHE’, true); must be enabled to have the caching function.

    define( 'WP_CACHE', true );

    Author, are you sure if this is the case. If it is, I hope it will be pointed out in the installation instructions.

    In addition, I found that there is a cache file in the wp-content/cache directory, but the headers are X-Cache miss.

    Thanks for reaching out!

    Cache should indeed be enabled in wp-config.php, however during installation, Surge does this for you if the file is writeable. It will also create a file called wp-content/advanced-cache.php which is also necessary for page caching to work.

    If both those things are present on your site, but you are still not getting a cache hit, then changes are your request somehow unique, for example a unique cookie is set during the request, or perhaps you are logged in, or maybe a plugin is sending a “Cache-Control: no-cache” header. I could try and help you troubleshoot this further if you could share the URL of your site where the plugin is installed and activated.

    I’m sure WP_CACHE is true, and there is a wp-content/advanced-cache.php file created by surge.

    There are also cache files generated by surge in the cache directory wp-content/cache, but all the cache files are opened and found to contain “X-Cache”: “miss”.

    Hi there!

    I can see Surge is working fine on your site. However, the reason for the cache misses is because there are unique cookies being issued, like this:

    Cookie: Hm_lvt_26f6623317fb29421825469cff442905=1639203948; Hm_lpvt_26f6623317fb29421825469cff442905=1639203948

    This causes the page cache to not work. It’s likely coming from a theme or plugin, some script perhaps. If you can remove that, you will get cache hits.

    Hope that helps!
