Full page caching is not a cosmetic optimisation. Users expect quick load times, and search engines reward fast websites with higher rankings. Full page caching supports both by storing fully rendered HTML pages, so the server does not have to rebuild the page from scratch for each visitor.
How Full Page Caching Enhances Performance and Capability
By caching full HTML pages, you create a snapshot of a page at a particular moment. When a user requests that page, the server can deliver the snapshot instead of generating the page again. This saves compute and database resources, allowing your server to handle more users simultaneously. The result is straightforward: faster load times for users and less strain on the server.
Real-World Impact
Our early adopters have reported clear improvements in website speed and server performance. One client saw a 40% reduction in server load and a 20% increase in page load speed. Those results point to a better user experience and potentially higher conversion rates.
Challenges with Magento 1 and How We Solved Them
Magento 1 presents specific challenges for full page caching, and our plugin handles them directly.
Mini Cart Issue
The mini cart needs to show real-time data, which makes it a barrier to full page caching. Our plugin uses targeted AJAX calls to fetch this data only when required, reducing unnecessary load on the server.
Form Key Problem
Magento 1 uses form keys to prevent CSRF attacks, but those keys make caching difficult. Our plugin replaces form keys with a strict referrer check, which is secure and cache-friendly.
Additional Features
- Automatic Expires Headers: You do not need to manually set expiration times for your cache; our plugin does it for you.
- Cache Tagging: This allows for precise cache management. When you update a product, only the relevant cached pages are flushed, keeping the process efficient.
The plugin is available for download, with the aim of improving performance and increasing server capability on Magento 1 stores.
