Alter Articles Cache

Advanced view caching replacement for Joomla Articles and Tags, delivering smarter cache control, selective invalidation, and improved performance.

Advanced view caching for Joomla Articles & Tags

This plugin replaces Joomla’s default view caching behavior for Articles and Tags, solving two major limitations out of the box.

By default, Joomla disables view caching for logged-in users - even when the displayed content is identical to guests. In addition, any update to articles or tags triggers a full cache purge, forcing unnecessary regeneration of all cached pages.

This extension fixes both issues.

Smarter caching for logged-in users

Enable view caching for logged-in users while maintaining full control. You can fine-tune caching behavior by:

• Specific items
• User groups
• Access levels
• Menu items

Easily separate cache versions for guests vs. logged-in users—or go further with fully granular control per user group or access level combination.

Precise, selective cache invalidation

No more full cache resets.

Only affected cache entries are cleared when content changes:

• New article created → clears cache only where the article may appear (article category pages, parent categories, article tags)
• Article updated → clears cache only for relevant views (article page, article category, parent categories, tags)

This dramatically reduces cache rebuild time and improves performance.

Built for performance

The result is significantly faster page generation times - especially for large category pages with many articles, tags, and custom fields.

Flexible cache cardinality

Control how many cache variations are stored:

• Single version (shared)
• Guest vs. logged-in split
• Fully segmented by user groups and access levels

You decide the balance between performance and personalization.

Consistent timezone handling

Optionally display all article dates in a single predefined timezone instead of per-user timezone (Joomla default).

Why it matters:

• Prevents unnecessary cache fragmentation caused by multiple timezones
• Keeps cache efficient with fewer variations
• Ideal when only dates (not exact times) are displayed

For most websites, showing dates in a consistent timezone (e.g., your site’s location) is both practical and expected.

File cache bucketing for large sites

When using Joomla’s file cache handler, the plugin can automatically organize cached files into separate subfolders (“buckets”) based on item IDs.

This prevents thousands of cache files from piling up in a single server folder, improving filesystem performance and keeping your server organized - even on large sites with hundreds of thousands of articles and tags.

In short

Faster pages, smarter cache control, and no unnecessary cache rebuilds.
