Add that the Standardwrapper container is for the servlet wrapper, all request resources can be divided into 4 different types, static resource requests (HTML, images, CSS, etc.), JSP requests, servlet requests,            and CGI requests. For different requests Tomcat handles the static resource file with Webdavservlet, Jspservlet processes the JSP request, and Cgiservlet handles the CGI request. ================jioendpoint Processing Request ================== ======= explanation ========guess because the HTTP protocol used is 1.1, so the last one to use is Http11protocol.
