Running Spring Cloud Gateway on Traditional Servlet Containers: MVC Support Explained

This article explains why Spring Cloud Gateway originally required Netty and could not run in traditional Servlet containers, introduces the new MVC Servlet support added in Spring Cloud 2023 (Gateway 4.1), and provides step‑by‑step instructions for configuring dependencies, routing rules, and custom filters using Tomcat or other servlet containers.

Resolving Duplicate Access‑Control‑Allow‑Origin Header Issues in Spring Cloud Gateway

This article explains why Spring Cloud Gateway can return duplicate Access‑Control‑Allow‑Origin and Vary headers during CORS handling, analyzes the underlying processing flow, and provides two practical solutions—using DedupeResponseHeader configuration or implementing a custom GlobalFilter—to ensure a single, correct header is sent to the client.

How Spring Cloud Gateway Initializes and Resolves Route Predicates

This article explains how Spring Cloud Gateway (Hoxton.SR11) initializes predicate factories, binds their Config objects from configuration, creates Route objects, caches them with CachingRouteLocator, and finally matches incoming requests by evaluating combined asynchronous predicates to locate the appropriate route.
