DCDN — Dynamic CDN · Whole Site Acceleration · QUIC · WebSocket · Mixed Traffic

CDN for
everything your
app does.

Static CDN accelerates files. DCDN accelerates your entire application — APIs, real-time data, POST requests, WebSocket connections, and all your static assets, simultaneously. One domain configuration handles all traffic types with intelligent routing and caching at the edge.

The Problem with Static CDN

Static CDN stops working the moment your users do anything dynamic.

A standard CDN can only accelerate content that can be cached — files that don't change per user. The moment users log in, submit forms, open WebSocket connections, or call APIs, static CDN steps aside. Your application slows down exactly when engagement is highest.

Static CDN only

What gets accelerated:

GET /main.css · image.jpg · bundle.js
GET /logo.svg · fonts.woff · icons.png

What does NOT get accelerated:

POST /api/checkout — bypasses CDN entirely
WebSocket /live — not supported
GET /api/user/42 — personalised, no cache
QUIC connections — unsupported
Result: every dynamic request crosses the full network distance to your origin — no acceleration, full latency.
With DCDN — Whole Site Acceleration

What gets accelerated:

GET /main.css · image.jpg · bundle.js (cached)
POST /api/checkout (dynamic route)
WebSocket /live (persistent connection)
GET /api/user/42 (optimised path to origin)
QUIC + HTTP/2 connections (all protocols)
Result: every request — static or dynamic — travels the shortest, fastest path to its destination.
Product Capability

Dynamic acceleration built for modern applications

DCDN extends static CDN with intelligent dynamic routing — keeping cacheable content at the edge while routing uncacheable requests through the fastest available network path to your origin.

All
Traffic types handled
Static files, dynamic API calls, POST requests, WebSocket connections, QUIC — all from one domain configuration.
0
Code changes needed
Change your DNS CNAME to NubexCloud CDN. Your application doesn't know or care — DCDN intercepts and classifies traffic automatically.
60%
Origin load reduction
Static content still served from edge cache. Only truly dynamic, uncacheable requests reach your origin — dramatically reducing origin server load.
Multi
Protocol support
QUIC, WebSocket, HTTP/2, and standard HTTP/HTTPS — all supported simultaneously on the same acceleration domain.
How It Works

Three phases. One intelligent acceleration layer.

DCDN operates transparently between your users and your origin — intercepting every request, making a routing decision in milliseconds, and delivering the optimal response.

1
Intercept

Request arrives at the nearest edge node

When a user's browser or app makes any request — GET, POST, WebSocket, QUIC — it is first intercepted by the nearest NubexCloud edge node. This interception happens transparently via DNS routing; the user's application sends to your domain, DCDN receives it at the edge.

📱 any request DNS → edge Edge Node Dubai · nearest intercepted ✓ 🖥 origin Origin not contacted yet
2
Classify

Intelligence layer: static or dynamic?

The edge node evaluates the request against your cache rules. Static content (CSS, JS, images, fonts) matching your rules is checked for a cache hit and served immediately. Dynamic content (API responses, personalised data, uploads) is marked for routing — it cannot be served from cache and must reach your origin, but via the optimal path.

Classify Static or dynamic? check cache rules request → cache → route GET /img.jpg → cache POST /api/pay → route WS /live → persist
3
Deliver

Optimal delivery for every request type

Static content is served directly from the edge node's cache — sub-millisecond, no origin contact. Dynamic content is forwarded to your origin server via the fastest available network path — selected in real time from routing tables maintained across all edge nodes. QUIC and WebSocket connections are maintained persistently at the edge.

Static path → from edge cache ~12ms Dynamic path → via optimal route ~48ms Without DCDN (direct) 480ms 10× faster for dynamic requests via DCDN
Protocol Support

Modern protocols. Built in. No configuration.

DCDN supports every protocol that modern applications require — including protocols that didn't exist when most legacy CDN infrastructure was designed.

Platform Features

Every control your application needs.

DCDN inherits all static CDN features — caching, SSL, access control, monitoring — and adds the dynamic routing and protocol capabilities that modern applications require.

Dynamic Route Optimization

For every dynamic request, DCDN selects the lowest-latency path from the edge node to your origin in real time — using live routing tables maintained across the entire edge network. Avoids congested internet paths and routes through private backbones where available.

Intelligent Cache Rules

Define which URLs, file types, or request patterns are cacheable vs dynamic. DCDN applies your rules automatically — no request-by-request configuration. Override with response headers, or manage TTL per path prefix, extension, or query string.

Access Control and Security

IP allowlists and blocklists, referer restriction, token authentication — all applied at the edge before requests reach your origin. HTTPS enforcement and custom SSL certificate management included for all acceleration domains.

Real-Time Monitoring

Live dashboards for bandwidth, request count, cache hit rate, and HTTP status codes — separately for static and dynamic traffic. Request count monitoring distinguishes between static HTTPS, dynamic HTTP/HTTPS, and QUIC requests for accurate cost tracking.

Content Refresh & Prefetch

Invalidate cached static content instantly across all edge nodes on deployment. Prefetch new static content to edges before users request it. For dynamic content, back-to-source configuration controls how and when DCDN fetches fresh content from your origin.

Log Download and Analytics

Per-edge access logs available for download — including request type, origin, protocol, latency, and status code. Statistical analysis dashboards aggregate across all DCDN domains. Integrate with your existing observability stack via log forwarding.

Use Cases

Built for applications that do more than serve files.

DCDN is for any application where users interact, not just browse — where a single session mixes static loads, API calls, real-time updates, and uploads.

SaaS Platforms and APIs
Dashboard loads (static), real-time data polling (dynamic API), file uploads (POST), WebSocket notifications — DCDN handles the entire session. Your users experience one fast, consistent application, not a mix of cached and uncached responses.

Finance · Payments
Financial Services and Payments
Payment forms, pricing data, transaction APIs, and real-time balance updates — all require acceleration without stale caching. DCDN routes financial API calls through the lowest-latency path while still caching static resources at the edge. Supports strict HTTPS enforcement and token access control.

Online Gaming and Real-time Apps
Game clients load assets (static CDN), match data flows over WebSocket (DCDN persistent connection), player actions are POST requests to game servers (DCDN dynamic route). One acceleration configuration handles the entire game session, from lobby to gameplay to leaderboard.

EdTech · Live learning
Online Education and Live Streaming
Video content (static CDN), live class sessions (WebSocket), quiz submissions (POST), student progress APIs (dynamic) — education platforms have the most complex content mix of any industry. DCDN unifies all of it under a single acceleration domain with zero routing complexity for developers.

Billing

Three billing dimensions. Choose what fits your traffic pattern.

DCDN billing has a unique dimension not in static CDN — request count. Because dynamic content cannot be cached, the system charges separately for the volume of requests routed through it. All three billing dimensions apply simultaneously.

"We had a static CDN and thought we were accelerated. Then we looked at API latency — 380ms average because our checkout and dashboard APIs had no CDN at all. Switching to DCDN dropped API response time by 8× and eliminated our origin overload issues completely."

"Our WebSocket game state updates went from 220ms to 38ms. QUIC's packet loss recovery made a massive difference for players on mobile networks in the Gulf. The connection drop rate fell from 3.2 to 0.1 per session — basically eliminated disconnect as a player issue."
