I would like to ask what is the difference between Apache web server and apache Tomcat?

Question

Recently I am studying an open source system called exoplatform. In this open source system, several of them need to start Apache Web Server and Tomcat Server
Why do we need to start Apache WebServer after having Tomcat?
What is the difference between these two Servers?

Answer 1

1. Apache itself only supports static pages, and can support php, etc. through plug-ins. Tomcat is just a servlet container.

2. Generally, when apache + tomcat are used together, apache acts as a static page proxy server + tomcat forwarding server, and dynamic requests (such as interfaces, jsp pages, etc.) are forwarded to tomcat.
