What Is a CMS & Cache Detector?
A CMS & Cache Detector is a website analysis tool that identifies the content management system, content delivery network, caching layers, and related technologies behind any public website. The HostsNiX CMS & Cache Detector functions as a technology profiler, CMS identifier, CDN checker, and caching header analyzer that helps administrators, developers, and SEO professionals understand how a website is built and delivered. Knowing which CMS and caching technologies a site uses is essential for troubleshooting performance issues, planning migrations, auditing security posture, and optimizing content delivery for global audiences.
Common CMS & Caching Issues We Detect

Developers
Understand the technology stack before migrations, integrations, or debugging performance issues.
SEO Professionals
Identify caching misconfigurations and CMS factors that affect crawlability and page speed scores.
Agencies
Audit client websites quickly to assess infrastructure, caching strategy, and optimization opportunities.
System Administrators
Validate CDN and caching deployments, confirm server configurations, and monitor technology changes.
What the Tool Detects
The HostsNiX CMS & Cache Detector scans for a wide range of technologies and signals:
CMS, CDN & Cache Overview
Common technology combinations and their typical caching strategies:
| CMS / Platform | CDN | Caching Layer | Typical Strategy |
|---|---|---|---|
| WordPress | Cloudflare | LiteSpeed Cache | Full-page and object caching for dynamic CMS sites |
| Drupal | Fastly | Varnish | Reverse-proxy caching for enterprise content platforms |
| Shopify | Shopify CDN | Built-in edge cache | Managed ecommerce with global asset delivery |
| Static Site | Netlify / Vercel | Edge CDN | Pre-built assets served from distributed edge nodes |
| Custom App | AWS CloudFront | Redis | Application-level caching with CDN for static assets |
| Magento | Akamai | Full-page cache | Ecommerce caching with CDN for media and static files |
Caching Headers Explained
HTTP caching headers control how browsers, proxies, and CDNs store and serve website content:
| Header | Example Value | Purpose |
|---|---|---|
| Cache-Control | max-age=31536000, public | Defines how long browsers and CDNs may cache a resource |
| Expires | Thu, 31 Dec 2026 23:59:59 GMT | Legacy header specifying an absolute expiration date |
| ETag | "abc123def456" | Entity tag for conditional requests and cache validation |
| Last-Modified | Wed, 15 Jan 2025 10:00:00 GMT | Timestamp used to determine if content has changed |
| Vary | Accept-Encoding | Tells caches which request headers affect the response variant |
| Age | 3600 | Indicates how long a response has been in a shared cache (seconds) |
| X-Cache | HIT from cloudfront | CDN-specific header showing whether the response was served from cache |
| Pragma | no-cache | Legacy HTTP/1.0 directive, largely replaced by Cache-Control |
