🚀 Caching Configuration Guide

🔍 Overview

Caching is a critical component for optimizing performance in web applications. By storing frequently accessed data temporarily, caching reduces latency and server load. This guide explains how to configure caching settings effectively.

📝 Key Concepts

• Cache Types:

  • In-Memory Cache: Fast but limited by RAM size.
  • Disk-Based Cache: Larger storage capacity but slower access.
  • Distributed Cache: Ideal for scalable systems (e.g., Redis or Memcached).

• TTL (Time-to-Live): Define how long cached data remains valid.

• Cache Control Headers: Use Cache-Control, ETag, and Expires to manage caching behavior.

🛠️ Configuration Options

1. Enable Caching

   Cache-Control: public, max-age=3600
   

2. Set Cache Size
   • Example: Cache-Size: 1024MB
3. Specify Cache Storage Type
   • Use /Documentation/en/Performance_Settings/Cache_Types for detailed options.

🧠 Best Practices

✅ Use Appropriate TTL: Avoid stale data by aligning TTL with content update frequency.
✅ Monitor Cache Hit/Miss Rates: Optimize performance by analyzing cache efficiency.
✅ Implement Cache Validation: Use ETag to ensure clients fetch updated data when necessary.
