Tomcat is not just a Servlet container, it also has the function of a traditional web server: processing Html pages.

Tomcat occupies small system resources when running, has good scalability, and supports functions commonly used in development application systems such as load balancing and email services. Therefore, it is deeply loved by Java enthusiasts and has been favored by some software developers. Recognition, like Apache, has long become a mainstream web server.

When you are working on web projects, most of them require http protocol, which is based on request and response. For example, if you enter a line of content search in Baidu,
then how does Baidu server handle this request? It needs to create a servlet To handle, servlet is actually a java program, just a java program on the server side.
The servlet intercepts your request through the configuration file, processes it accordingly, and then displays the corresponding interface to you. So how to create a servlet? Tomcat is used at this time.
It is what helps you create servlets, so it is also called a web container. Without it, you cannot run web projects. There are many corresponding web containers,
such as JBOSS, WEBLOGIC, etc.
Tomcat is an application server. He can run the Java program you wrote according to the Servlet specification in J2EE.
Simply put, it is a running container for a Web website. You can put the website you have written into it and run it.
Tomcat is an application (java) server. It is just a servlet container and an extension of Apache to handle the dynamic web page part.

The role of Tomcat

Tomcat is a free open source Web application server. It is a lightweight application server and is commonly used in small and medium-sized systems and situations where there are not many concurrent access users. It is the first choice for developing and debugging JSP programs.
When the Apache server is configured on a machine, it can be used to respond to access requests for HTML (an application under the Standard Universal Markup Language) page. In fact, the Tomcat part is an extension of the Apache server, but it runs independently, so when you run tomcat, it actually runs as a separate process from Apache.
The trick is that when configured correctly, Apache serves the HTML pages and Tomcat actually runs the JSP pages and Servlets.
In addition, Tomcat, like IIS and other web servers, has the function of processing HTML pages. In addition, it is also a Servlet and JSP container. An independent Servlet container is the default mode of Tomcat.
However, Tomcat's ability to handle static HTML is not as good as the Apache server.
