Caching the Uncacheable
summary
Describes how to cache personalized pages by generating and serving separate representations for defined user groups instead of disabling caching. Covers HTTP validation and freshness, trusted proxy configuration, handling session cookies and Vary-based content negotiation, and where to apply compression so proxies can cache compressed responses. Demonstrates an implementation using Symfony HTTP Cache and Varnish, including surrogate keys and pre/post response hooks to purge or vary cached entries for different browsers and feature flags.
