This paper delves into the "Request header is too large" error encountered in Tomcat servers, typically caused by oversized HTTP request headers. It first analyzes the root causes, noting that while the HTTP protocol imposes no hard limit on header size, web servers like Tomcat set default restrictions. The paper then focuses on two main solutions: optimizing HTTP method selection by recommending POST over GET for large data transfers, and adjusting server configurations, including modifying Tomcat's maxHttpHeaderSize parameter or Spring Boot's server.max-http-header-size property. Through code examples and configuration instructions, it provides practical steps to effectively avoid this error, enhancing the stability and performance of web applications.
