Adding dynamic features to an aggressively cached website

Read Original

This technical article details how to implement dynamic user-specific features on a heavily cached website. The author, who runs a Django blog behind Cloudflare, demonstrates adding admin-only edit links and a persistent random post navigation system within tags. Both solutions cleverly use client-side localStorage and JavaScript to work around full-page caching, with code examples and implementation logic provided.
