Xiaobian to share with you what is the difference between apache and apache tomcat, I believe most people do not know how, so share this article for your reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

Let's start with Apache and Apache Tomcat.

Apache is a web server (static parsing such as HTML), tomcat is a java application server (dynamic parsing such as JSP)

Apache is a Web server software, there are many products, can support SSL technology, support multiple virtual hosts. It is fast, reliable, and extensible with simple APIs to compile interpreters such as Perl/Python into the server. Apache is characterized by simplicity, speed, stable performance, and can be used as a proxy server. It can run on most computer operating systems and is widely used due to its cross-platform and security features.

Tomcat is just a servlet container, which can be considered an extension of apache, but can run independently of apache.

Tomcat is a core project of the Apache Software Foundation's Jakarta project, developed by Apache, Sun, and other companies and individuals. Thanks to Sun's involvement and support, 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.

Tomcat server is a free open source Web application server, belongs to lightweight application server, in small and medium-sized systems and concurrent access to users is not a lot of occasions are commonly used, is the development and debugging JSP program of choice.

The two can be compared from the following points:

Both were developed by Apache.

2. Both have HTTP service functions

Both are open source and free.

Contact:

(1) Apache is an ordinary server, which only supports html, that is, ordinary web pages. It can support php through plug-ins and can also communicate with Tomcat (Apache connects Tomcat in one way, that is, Tomcat resources can be accessed through Apache, otherwise).

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

Apache and Tomcat integration

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 JSP and other web page codes, and returns them to the Apache server, and then returns them to the browser via Apache.

This is because jsp is server-side interpretation code, Tomcat only does dynamic code parsing, Apache returns parsed static code, Apache+Tomcat integration can reduce Tomcat service overhead.

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

Difference:

Apache is implemented in C and supports various features and modules to extend core functionality;Tomcat is written in Java and better supports Servlets and JSP.

Apache is a Web server, Web servers serve pages that browsers can browse, Web servers specifically handle HTTP requests, but application servers serve business logic for applications through many protocols.

Tomcat is an application server that runs on Apache and provides methods that client applications can call. It's just a servlet container that can be considered an Apache extension, but can run independently of Apache.

Apache is an ordinary server, which only supports html static ordinary web pages. However, PHP can be supported through plug-ins, and Tomcat can also be connected (one-way Apache connection Tomcat, that is, Tomcat resources can be accessed through Apache, otherwise), Tomcat is a jsp/servlet container, and also supports HTML, JSP, ASP, PHP, CGI, etc., wherein CGI requires some manual debugging, but it is very easy.

Apache focuses on http server, Tomcat focuses on servlet engine, if run in standalone mode, Tomcat and apache support JSP equivalent in function, but it is not ideal for static web pages.

Apache can run for a year without restarting, stability is very good, and Tomcat is not necessarily.

5, the preferred web server is Apache, but Apache can not resolve the jsp, servlet only use tomcat.

Apache is the very beginning of the page parsing service, tomcat is developed later, essentially tomcat's function can completely replace Apache, but Apache is tomcat's predecessor, and there are many people on the market still using Apache, so Apache will continue to exist, will not be replaced, apache can not parse java things, but parsing html speed is fast.

Integration of both:

Apache is a web server environment program, enabling him to be used as a web server, but only supports static web pages, does not support dynamic web pages, such as asp, jsp, php, cgi

If you want to run jsp in Apache environment, you need an interpreter to execute jsp web pages, and this jsp interpreter is Tomcat.

So why JDK? Because jsp needs to connect to the database, jdk is required to provide the drive to connect to the database, so APACHE+TOMCAT+JDK is required to run the web server platform of jsp.

Benefits of integration:

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. Because jsp is server-side interpreted code, this integration reduces Tomcat service overhead.

The above is apache and apache tomcat difference is what all the content, thank you for reading! I believe that everyone has a certain understanding, hope to share the content to help everyone, if you still want to learn more knowledge, welcome to pay attention to the industry information channel!
