What is Tomcat:

Tomcat is a core project of the Jakarta project of the Apache Software Foundation (Apache Software Foundation), which is jointly developed by Apache, Sun and other companies and individuals. With the participation and support of Sun, the latest Servlet and JSP specifications are always reflected in Tomcat, and Tomcat 5 supports the latest Servlet 2.4 and JSP 2.0 specifications. Because of its advanced technology, stable performance and free, Tomcat is deeply loved by Java enthusiasts and recognized by some software developers, and has become a popular Web application server.

Advantages of Tomcat:

1. It has both expandability and security of du. If the number of access requests zhi increases sharply per unit time, you can use a relatively low fee dao to increase the front-end capacity.

2. It is easy to expand. Because it is a single servlet container running on this powerful server, there is no need to consider complex issues such as the maintenance of session state in a distributed environment.

3. The back-end server is not accessible to the outside world, and the hackers on the Internet can only access the front-end web server, but not the back-end application server directly, which improves the security. But this does not mean that hackers cannot carry out other forms of attack through web browsers.

The role of tomcat:

1. Tomcat is a free and open source Web application server, which is a lightweight application server. It is widely used in small and medium-sized systems and not many concurrent access users. It is the first choice for developing and debugging JSP programs.

2. When an Apache server is configured on a machine, it can be used to respond to requests for access to HTML (an application under the standard general markup language) pages. The Tomcat part is actually an extension of the Apache server, but it runs independently, so when you run tomcat, it actually runs as a separate process from Apache.

3. The trick is that when configured correctly, Apache serves the HTML page, while Tomcat actually runs the JSP page and Servlet.

4. In addition, Tomcat, like Web servers such as IIS, has the function of dealing with HTML pages. In addition, it is also a Servlet and JSP container, and an independent Servlet container is the default mode of Tomcat.

5. However, Tomcat is not as capable of handling static HTML as Apache servers.
