Cache

This server gives Claude five tools for debugging and optimizing web caching. It can analyze HTTP cache headers and grade them A+ through F with specific fixes, generate deterministic cache keys for Redis or Memcached with URL normalization and body hashing, simulate LRU/LFU/FIFO/TTL eviction policies side by side with hit rates, detect which CDN is serving a resource and whether it was a cache hit, and analyze what a browser would cache from a page with bandwidth savings estimates. Reach for it when you're diagnosing cache misses, comparing eviction strategies, or need to explain why a CDN configuration isn't working as expected.
