DJIA Cache – Storage Tab

The Storage tab allows you to configure where DJIA Cache stores its cache files and verify whether required WordPress performance drop-ins are installed correctly.

Sections included in this tab:

  • Cache Storage
  • Installed Drop-ins

Cache Storage

This section defines the directories where DJIA Cache stores different types of cached data.

Proper cache storage configuration ensures that cached files are organized correctly and can be served efficiently.

Page cache directory

Defines the directory where HTML page cache files are stored.

Example default location:

WP_CONTENT_DIR/cache/djia/pages/

These files contain fully generated HTML pages that can be served instantly to visitors without executing WordPress PHP.

Assets cache directory

Defines the directory used to store optimized asset files, including:

  • minified CSS
  • minified JavaScript
  • generated asset variants

Example location:

WP_CONTENT_DIR/cache/djia/assets/

This helps reduce processing overhead by storing optimized versions of static files.

Object cache directory

Defines where persistent object cache data is stored.

Example location:

WP_CONTENT_DIR/cache/djia/object/

Object cache files store database query results and WordPress objects to reduce repeated database queries.

Installed Drop-ins

This section verifies whether DJIA Cache performance drop-ins are properly installed.

Drop-ins allow WordPress to load caching features before the normal plugin loading process, which improves performance.

advanced-cache.php

Used for early page cache delivery.

Example location:

wp-content/advanced-cache.php

This drop-in allows DJIA Cache to serve cached HTML pages before WordPress fully initializes, resulting in faster response times.

object-cache.php

Used for persistent object caching.

Example location:

wp-content/object-cache.php

When installed, this drop-in enables WordPress to store database query results and other objects between requests.

Benefits:

  • fewer database queries
  • improved backend performance
  • faster page generation

Cache base directory

All DJIA Cache storage directories are typically located inside:

WP_CONTENT_DIR/cache/djia/

This directory contains subfolders for:

  • page cache
  • asset cache
  • object cache

⚠ Important

Do not manually delete cache files from these directories while the plugin is active unless performing maintenance or debugging.

Use the DJIA Cache purge tools instead.
