What is the difference between apache and tomcat

What is the difference between apache and tomcat?

Common points:

1. Both are developed by the apache organization

2. Both have the function of HTTP service

3. Both are free

Differences:

1. Apache supports static pages, and tomcat supports dynamic ones, such as servlets, etc. .

2. Apache is a web server (static parsing, such as HTML), and Tomcat is an application (java) server (dynamic parsing, such as jsp, asp, php, cgi). It is just a servlet (jsp is also translated into servlet) container, which can be considered an extension of Apache, but can run independently of Apache.

3. Apache is implemented in C language and supports various features and modules to extend core functions; Tomcat is written in Java and better supports Servlet and JSP.

Association:

1) Apache is an ordinary server. It only supports HTML, which is ordinary web pages. It can support PHP through plug-ins and can also be connected to Tomcat (Apache is one-way Connecting to Tomcat means that Tomcat resources can be accessed through Apache, but not vice versa).　　

　2) Apache only supports static web pages, but dynamic web pages like Jsp require Tomcat to process.

3) Integration 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, parses the parsed JSP and other web page codes and sends it back to the Apache server, and then returns it to the browser via Apache.

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

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

Visual example:

Apache is a car, which can hold some things such as html, etc., but cannot hold water. Water must have a container (bucket), and this bucket does not need to be placed on the truck, then this bucket is TOMCAT.

Apache: It is implemented in C language and is specially used to provide HTTP services.

Features: Simple, fast, stable performance, configurable (proxy)

1. Mainly used to parse static text, with high concurrency performance, focusing on HTTP services ;

2. Supports static pages (HTML), but does not support dynamic requests such as: CGI, Servlet/JSP, PHP, ASP, etc.;

3. It has strong scalability and can PHP is supported through plug-ins, and one-way Apache connection to Tomcat can be achieved to achieve connectivity;

4. Apache is the world's number one web server.

Tomcat: It is a JSP server (Servlet container) developed in Java that complies with the JavaEE Servlet specification and is an extension of Apache.

Features: Free Java application server

1. Mainly used to parse JSP/Servlet, focusing on Servlet engine;

2. Support static page, but the efficiency is not as high as Apache; supports Servlet and JSP requests;

3. Tomcat itself also has a built-in HTTP server to support static content, which can be integrated with Apache through Tomcat's configuration management tool.
