Zwerfkei Cloudflare Cache¶

What is Cloudflare Cache?¶

Cloudflare Cache is a globally distributed caching system that stores static and dynamic content on edge servers close to end users. By caching content on these edge locations:

• Reduces load on origin servers
• Accelerates load times by serving content closer to users
• Improves scalability of applications
• **Reduces b
• andwidth costs** by minimizing requests to the origin

How does it work?¶

sequenceDiagram
    participant User as User
    participant Edge as Cloudflare Edge
    participant Origin as Origin Server

    User->>Edge: Request for content
    alt Content in cache
        Edge-->>User: Cached content (fast)
    else Content not in cache
        Edge->>Origin: Request to origin
        Origin-->>Edge: Response
        Edge->>Edge: Cache content
        Edge-->>User: Fresh content
    end

When a user requests content: 1. The request arrives at the nearest Cloudflare edge datacenter 2. Cloudflare checks if the content is already cached 3. Cache HIT: Content is served directly from cache (very fast) 4. Cache MISS: Content is fetched from the origin server, cached, 5. and then served

What are Cache Rules?¶

Cache Rules are configuration settings that determine which content is cached, how long it remains cached, and under what conditions the cache is used. They replace the older Page Rules for caching configuration and offer more flexibility.

Benefits of Cache Rules¶

• ✅ Precision: Fine-grained control over caching behavior per URL, file type, or custom criteria
• ✅ Performance: Optimal cache configuration per content type
• ✅ Flexibility: Combination of multiple conditions
• and actions
• ✅ Priority: Control over the order in which rules are applied
