uwebsockets/examples/Headers.js

Fastest uWebSockets server for Node.js – µWebSockets outperforms Socket.IO & Fastify. Built in C++ for high-performance networking & pub/sub.

/* Example of looping over all headers (not recommended as production solution,
 * do NOT use this to "solve" your problems with headers, use ONLY for debugging) */
