Reverse Proxy Deep Dive: Connection Management Challenges and Evolution
2025-07-12
This article delves into the inner workings of a reverse proxy and the complexities of connection management. From single-threaded to multi-threaded, multi-process, and event-driven architectures with socket sharding, reverse proxies have evolved significantly to handle high concurrency. The article details the advantages and disadvantages of various techniques, such as the efficiency of epoll in I/O multiplexing and the challenges of multi-threaded models with multi-core processors, and points out further complexities in supporting TLS and protocol diversity.
