What this post added

This post details the application of Cloudflare Workers for technical SEO, specifically addressing common obstacles like platform restrictions, legacy tech stacks, and incorrect builds. It introduces a filter chain architecture for modifying incoming requests and outgoing responses, including response bodies. Practical examples include implementing redirects using Workers KV and Cuckoo Filters for scalability, and injecting Hreflang tags using a precomputed Boyer-Moore-Horspool algorithm on byte arrays, with further exploration into Rust WASM for performance gains.
