By Enabling the Back/Forward Cache (bfcache) For Your Magento Store
Modern web browsers like Chrome, Firefox, and Safari contain a powerful, built-in optimization called the Back/Forward Cache (bfcache). It's designed to do one thing exceptionally well: make navigating back and forth between pages instantaneous. When a user clicks a link and then hits the "back" button, bfcache restores a complete, in-memory snapshot of the previous page, eliminating the need for any network requests. Considering that 1 in 10 navigations on desktop and 1 in 5 on mobile are back/forward actions, the cumulative performance gain is enormous.
Here's the critical issue for merchants: by default, Magento actively tells browsers not to use this feature. This decision creates a jarring, slow experience where users are forced to wait for pages to completely reload, even if they were just there a second ago. reload
This isn't a mistake; it's a safety measure rooted in the dynamic nature of e-commerce. Magento disables bfcache to prevent issues with stale data. For example, a cached page might show an incorrect mini-cart total or outdated stock information. This is primarily accomplished by sending a Cache-Control: no-store HTTP header, a blunt instrument that disables bfcache across the board. Data from HTTPArchive suggests that a staggering 89% of Magento sites are affected by this, leaving a massive performance opportunity untapped. This, combined with legacy JavaScript patterns like unload event listeners, effectively blocks your store from leveraging one of the web's most significant speed enhancements.
The JaJuMa Back/Forward Cache extension is the expertly engineered solution that bridges the gap between Magento's safety-first approach and the modern user's demand for instant performance. As the very first agency to develop a bfcache solution for Magento 2, we have an unparalleled understanding of the technical challenges and have crafted the definitive tool to overcome them.
Our extension doesn't just blindly enable bfcache; it intelligently navigates Magento's complexities to deliver speed without compromising data integrity. It works by:
Applying Smart Exclusions: The extension automatically prevents caching on sensitive routes like /cart, /checkout, and /customer/*, ensuring dynamic, user-specific data is always fresh and secure.
Handling Dynamic Content: We've engineered specific logic to manage elements like the mini-cart. It can be configured to update only after a user interacts with the restored page, preserving the lightning-fast load while ensuring data accuracy when it matters most.
Resolving Core Blockers: Our code safely works around the default Magento blockers, allowing the vast majority of your store's pages—categories, products, and CMS pages—to benefit from instant loads.
This extension is a no-brainer, quick-win optimization that unlocks a level of performance and user experience impossible to achieve with a default Magento or Hyvä installation.

Performance & Usability Boost for your Magento store
To grasp the transformative impact of this extension, it's essential to understand what the Back/Forward Cache (bfcache) is and why it's fundamentally different—and superior—to other forms of caching.
When you navigate from Page A to Page B, a standard browser discards Page A. If you click the "back" button, the browser must start from scratch: sending requests to the server, downloading assets, parsing HTML, CSS, and JavaScript, and re-rendering the entire page. This is a slow and resource-intensive process.
The bfcache changes this paradigm completely. Instead of discarding Page A, the browser takes a complete snapshot of it and stores it in-memory. This snapshot includes the fully rendered page, the entire Document Object Model (DOM), and even the state of all JavaScript variables (the JS Heap). Think of it like pausing a video game; when you unpause, you're right back where you left off, instantly.
Insight: Bfcache vs. Standard HTTP Cache
It's crucial not to confuse bfcache with the browser's standard HTTP cache.
The HTTP cache only stores individual files (like images, CSS, JS). When you revisit a page, the browser still has
to re-assemble these pieces and execute the code to render the page.
Bfcache, in contrast, stores the already assembled, fully rendered page. This is why a bfcache restore is always
faster than even the most well-optimized navigation that relies on the HTTP cache.
Enabling bfcache isn't just a technical tweak; it's a strategic business decision with a direct and measurable impact on your bottom line. By transforming a common navigation pattern from a frustrating delay into an instant interaction, you fundamentally improve your store's performance across key business metrics.
Google's Core Web Vitals (CWV) are designed to measure real-world user experience, and bfcache directly and dramatically improves them.
Faster performance and better Core Web Vitals are not just vanity metrics; they are proven drivers of e-commerce success. Extensive industry research has quantified the connection:
By unlocking bfcache, you are directly applying these proven principles to up to 20% of your mobile users' navigations, creating a tangible lift in engagement and sales.
| Metric | Without JaJuMa Bfcache (Typical Magento) | With JaJuMa Bfcache (Instant Navigation) | Business Impact |
|---|---|---|---|
| LCP (Largest Contentful Paint) | 1.6s (Real Case Study Data) | ~0.8s (-50%) on bfcache restore | Better UX, Improved SEO Ranking |
| CLS (Cumulative Layout Shift) | 0.3 (Real Case Study Data) | 0.0 (-100%) on bfcache restore | Flawless Visual Stability, Perfect CWV Score |
| User Experience | Jarring full-page reloads, waiting time | Instant, seamless navigation | Reduced Frustration & Bounce Rate |
| Conversion Rate Lift | Baseline | +8-10% (Industry Average) | Increased Sales & Revenue |
| Server Load | Request for every back/forward click | Zero server requests on restore | Lower Hosting Costs, Higher Stability |

You don't need to be a performance expert to use our extension safely. We've built in the necessary safeguards based on our experience optimizing hundreds of Magento stores.
For stores running high-performance hosting stacks, Varnish compatibility is non-negotiable. Our extension is fully compatible with Varnish. To ensure correct behavior and prevent Varnish from interfering with the headers that enable bfcache, simply update your vcl_deliver subroutine in your VCL file as follows.
Composer Installation? 
sub vcl_deliver {
# JaJuMa Bfcache Compatibility
if (resp.http.Cache-Control ~ "public") {
set resp.http.Cache-Control = "no-cache, must-revalidate,
max-age=0";
} else {
set resp.http.Cache-Control = "no-store, no-cache, must-revalidate,
max-age=0";
}
# End JaJuMa Bfcache Compatibility
#... other vcl_deliver logic
}
