The Fastest Way to Deliver Content

Deliver content with speed, scale, and security using Liferay DXP’s integrated CDN.

Get the Incredible Speed of a Built-In CDN

Deliver content instantly.

Provide sub-second page loads worldwide by serving content from the network’s edge. With faster delivery, you’ll reduce latency, improve SEO, and boost your Core Web Vitals.
  • Global edge caching. Your content is stored closer to your visitors, so pages load instantly—no matter where users are.
  • Smart traffic routing. Each client request is automatically routed to the nearby CDN server, taking the fastest path across the network, reducing time-to-first-byte (TTFB) and bounce risk.
  • Optimized images and media. Photos and videos get compressed, resized, and delivered efficiently through caching servers, ensuring fast delivery without losing visual quality.
  • Modern protocol delivery. Use advanced connection protocols that load multiple assets simultaneously—making your site feel snappy and modern.
  • Performance-tuned defaults. Preconfigured OOTB settings tuned for LCP, TTFB, and CLS benchmarks help you meet SEO performance thresholds.

Scale CDN performance to handle traffic surges.

Handle network spikes without downtime. Intelligently absorb sudden web traffic bursts at the CDN edge to maintain uninterrupted service and keep your site fast when it matters most.
  • Elastic edge capacity. Automatically manage sudden bursts without overprovisioning servers or scaling manually.
  • Origin shielding. The CDN fetches a requested file once, then shares it across all users, protecting your origin from “thundering herd” overload.
  • Stale-while-revalidate. Users get an immediate cached response while new content refreshes quietly in the background.
  • Global load balancing. Traffic is intelligently distributed across regions for consistent performance everywhere.
  • Edge surge protection. Built-in rate controls smooth out traffic spikes, keeping critical services online when demand soars. If one server goes offline, other operational servers can take over to maintain content availability.

Automatically refresh content when you make updates.

Ensure updated content is live worldwide the moment you publish it. With precise, automated cache purging, you can make updates visible instantly without manual effort.
  • Auto-purge on publish. New or updated content is refreshed worldwide within seconds – no tickets, no scripts.
  • Precise cache tags. Only modified assets are invalidated, preserving performance while keeping data fresh.
  • SEO-safe updates. Titles, metadata, and sitemaps update automatically so search engines always see the latest version.
  • Consistent experiences. Every visitor sees the same up-to-date content, eliminating confusion and rework.

Ensure a flawless user experience.

Serve files reliably with versioned and immutable URLs that eliminate broken or outdated content.
  • Automatic cache-busting. Users always see the newest version of each web page – hashed URLs ensure changes to files (like javascript file or images) appear instantly.
  • Immutable assets (long-lived caching for speed.) Versioned files can be cached long-term for faster reloads without risking stale content.
  • Responsive images. Automatically deliver the right image size for every device to reduce load time.
  • Edge-ready media policies. Designate public folders as cache-safe for faster delivery – no custom setup needed.
  • Signed links for private files. Deliver private files securely and quickly, balancing speed with protection.

Protect your network and users from attacks.

Our CDN is designed with website security in mind, helping you prevent malicious actions from slowing or taking down your site with our built-in WAF, rate limiting, and bot detection.
  • WAF presets. Get one-click protection for login pages and APIs that block common attacks, reducing risk and cutting down on incident noise.
  • Bot mitigation. Protect user accounts and your data at the edge by automatically challenging malicious bots attempting credential stuffing or content scraping.
  • Per-route rate limits. Apply specific guardrails to sensitive paths on your site, keeping the rest of the experience fast and stable during a targeted attack.
  • Encrypted by design. Transport Layer Security (TLS) at the edge ensures secure delivery everywhere, strengthening compliance and building user trust.
  • Reputation & policy controls. Known bad actors are filtered at the edge, cutting down on wasted resources and safeguarding your uptime.

Increase operational efficiency and transparency.

With our CDN, website owners can reduce bandwidth costs and bandwidth consumption, lighten your server load, and gain full insight into performance – all without extra tools or dashboards.
  • One-click cache profiles. Remove guesswork and boost cache hit rates with best-practice settings for pages, media, and APIs.
  • In-product visibility. View cache stats, TTLs (time-to-live), and purge logs directly in Liferay – no need to hunt across different tools.
  • Analytics deep links. Jump straight into provider dashboards for advanced insights and faster troubleshooting.
  • Authoring warnings. Prevent performance issues with real-time alerts for cache-unfriendly components.
  • Lower origin load. Offload more traffic to the edge, reducing infrastructure costs and improving stability.

What Is a CDN?

A Content Delivery Network (CDN) is a globally distributed system of servers positioned at the edge of the internet to deliver content from the location closest to each user. By caching and routing data across multiple points of presence, a CDN reduces latency, alleviates network congestion, and speeds up content delivery. CDN providers supply the infrastructure and IP addresses required for efficient request routing, ensuring faster load times and a smoother user experience.
