Quick googling finds this article (from a well-known author, but it is not official documentation): https://www.baeldung.com/spring-boot-max-http-header-size On that page there is a discussion about change in the property names in Spring Boot 3, and the names are different: with no "tomcat" part in them. (BTW, If you run Tomcat directly, without SpringBoot, its configuration expects a value as integer (bytes) and cannot handle a "KB" suffix The relevant settings in Tomcat itself are documented at https://tomcat.apache.org/tomcat-9.0-doc/config/http.html#Standard_Implementation Replace "9.0" in the URL with your version.) > > Another thing to check is how big your headers are.
