Tomcat is an open-source project, under the "Apache Software Foundation" (which also provides the most use, open-source, industrial-strength Apache HTTP Server).

The syntax of the message is defined in the HTTP specification.Īpache Tomcat is a Java-capable HTTP server, which could execute special Java programs known as "Java Servlet" and "Java Server Pages (JSP)".

In other words, HTTP is a pull protocol, a client pulls a page from the server (instead of server pushes pages to the clients). The server then returns a response message to the client.

A client sends a request message to the server.

The default port number assigned to HTTP is TCP port 80. The IP provides support for routing and addressing (via a unique IP address for machines connected to the Internet) while TCP supports multiplexing via 64K ports from port number 0 to 65535.
