This is a very brief history of web server programs, so some information necessarily overlaps with the histories of the web browsers, the World Wide Web and the Internet; therefore, for the sake of clarity and understandability, some key historical information below reported may be similar to that found also in one or more of the above-mentioned history articles.
Common Gateway Interface. In computing, Common Gateway Interface ( CGI) is an interface specification that enables web servers to execute an external program to process HTTP or HTTPS user requests. [1] Such programs are often written in a scripting language and are commonly referred to as CGI scripts, but they may include compiled programs. [2]
Apache Tomcat (called "Tomcat" for short) is a free and open-source implementation of the Jakarta Servlet, Jakarta Expression Language, and WebSocket technologies. [2] It provides a "pure Java" HTTP web server environment in which Java code can also run. Thus it is a Java web application server, although not a full JEE application server.
Server-side scripting is a technique used in web development which involves employing scripts on a web server which produces a response customized for each user's (client's) request to the website. Scripts can be written in any of a number of server-side scripting languages that are available (see below). Server-side scripting is distinguished ...
Web server software allows computers to act as web servers. The first web servers supported only static files, such as HTML (and images), but now they commonly allow embedding of server side applications. Some web application frameworks include simple HTTP servers. For example the Django framework provides runserver, and PHP has a built-in server.
Encapsulation is the computer-networking process of concatenating layer-specific headers or trailers with a service data unit (i.e. a payload) for transmitting information over computer networks. [2] [3] [4] Deencapsulation (or de-encapsulation) is the reverse computer-networking process for receiving information; it removes from the protocol ...
PHP is a general-purpose scripting language that is especially suited to server-side web development, in which case PHP generally runs on a web server. Any PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content or dynamic images used on websites or elsewhere. [282]
The Apache HTTP Server became the most-used web-server software, a title that still holds as of 2015. Systems based on a common "stack" of software with the Linux kernel at the base, Apache providing web services, the MySQL database engine for data storage, and the PHP programming language for providing dynamic pages, came to be termed LAMP ...
