Apache

Apache HTTP Server (abbreviated as Apache) is an open source web server of the Apache Software Foundation, which can run in most computer operating systems. Because of its multi-platform and security, it is one of the most popular Web server-side software. It is fast, reliable and can compile interpreters such as Perl/Python into the server through a simple API extension.

Apache HTTP server is a modular server, derived from NCSAhttpd server, after many modifications, it has become the number one Web server software in the world.

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 connection between apache and tomcat

1. Apache is an ordinary server, which only supports html, that is, ordinary web pages. You can support php through plug-ins, and you can also connect with Tomcat (Apache connects to Tomcat one-way, that is, you can access Tomcat resources through Apache, and vice versa).

2. Apache only supports static pages, but dynamic pages like Jsp need to be handled by Tomcat.

3. Integrated use of Apache and Tomcat

If the client requests a static page, only the Apache server is required to respond to the request; if the client requests a dynamic page, the Tomcat server responds to the request. The parsed JSP and other web page codes are parsed and transmitted back to the Apache server, and then returned to the browser through Apache.

This is because jsp interprets the code on the server side, Tomcat only does dynamic code parsing, and Apache sends back the parsed static code. Apache+Tomcat integration can reduce the service overhead of Tomcat.

4. Apache and Tomcat are independent and can be integrated on the same server.
