The Apache HTTP Server is a free and open-source cross-platform web server software, released under the terms of Apache License 2.0. It is developed and maintained by a community of developers under the auspices of the Apache Software Foundation.
The Comprehensive Perl Archive Network (CPAN) is a repository of over 250,000 software modules and accompanying documentation for 39,000 distributions, written in the Perl programming language by over 12,000 contributors. CPAN can denote either the archive network or the Perl program that acts as an interface to the network and as an automated software installer. Most software on CPAN is free and open source software.
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. Server-side scripting is distinguished from client-side scripting where embedded scripts, such as JavaScript, are run client-side in a web browser, but both techniques are often used together. The alternative to either or both types of scripting is for the web server itself to deliver a static web page.
In web applications, a rewrite engine is a software component that performs rewriting on URLs, modifying their appearance. This modification is called URL rewriting. It is a way of implementing URL mapping or routing within a web application. The engine is typically a component of a web server or web application framework. Rewritten URLs are used to provide shorter and more relevant-looking links to web pages. The technique adds a layer of abstraction between the files used to generate a web page and the URL that is presented to the outside world.
WebGUI is an open-source content management system written in Perl and released under the GNU General Public License.
OTRS is a service management suite. The suite contains an agent portal, admin dashboard and customer portal. In the agent portal, teams process tickets and requests from customers. There are various ways in which this information, as well as customer and related data can be viewed. As the name implies, the admin dashboard allows system administrators to manage the system: Options are many, but include roles and groups, process automation, channel integration, and CMDB/database options. The third component, the customer portal, is much like a customizable webpage where information can be shared with customers and requests can be tracked on the customer side.
Webmin is a web-based server management control panel for Unix-like systems. Webmin allows the user to configure operating system internals, such as users, disk quotas, services and configuration files, as well as modify and control open-source apps, such as BIND, Apache HTTP Server, PHP, and MySQL.
The Web Server Gateway Interface is a simple calling convention for web servers to forward requests to web applications or frameworks written in the Python programming language. The current version of WSGI, version 1.0.1, is specified in Python Enhancement Proposal (PEP) 3333.
In computing, a solution stack or software stack is a set of software subsystems or components needed to create a complete platform such that no additional software is needed to support applications. Applications are said to "run on" or "run on top of" the resulting platform.
LAMP is an acronym denoting one of the most common software stacks for the web's most popular applications. Its generic software stack model has largely interchangeable components.
Catalyst is an open source web application framework written in Perl, that closely follows the model–view–controller (MVC) architecture, and supports a number of experimental web patterns. It is written using Moose, a modern object system for Perl. Its design is heavily inspired by frameworks such as Ruby on Rails, Maypole, and Spring.
Web server software allows computers to act as web servers. The first web servers supported only static files, such as HTML, but now they commonly allow embedding of server side applications.
Nginx is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. The software was created by Russian developer Igor Sysoev and publicly released in 2004. Nginx is free and open-source software, released under the terms of the 2-clause BSD license. A large fraction of web servers use Nginx, often as a load balancer.
Resin is a web server and Java application server developed by Caucho Technology. There are currently only two versions available: Resin (GPL), which is free for production use, and Resin Pro, designed for enterprise and production environments with a licensing fee. Resin supports the Java EE standard and features a mod_php/PHP-like engine known as Quercus.
SPDY is an obsolete open-specification communication protocol developed for transporting web content. SPDY became the basis for HTTP/2 specification. However, HTTP/2 diverged from SPDY and eventually HTTP/2 subsumed all usecases of SPDY. After HTTP/2 was ratified as a standard, major implementers, including Google, Mozilla, and Apple, deprecated SPDY in favor of HTTP/2. Since 2021, no modern browser supports SPDY.
FastCGI is a binary protocol for interfacing interactive programs with a web server. It is a variation on the earlier Common Gateway Interface (CGI). FastCGI's main aim is to reduce the overhead related to interfacing between web server and CGI programs, allowing a server to handle more web page requests per unit of time.
Mojolicious is a real-time web application framework, written by Sebastian Riedel, creator of the web application framework Catalyst. Licensed as free software under the Artistic License v 2.0, it is written in the Perl programming language, and is designed for use in both simple and complex web applications, based on Riedel's previous experience developing Catalyst. Documentation for the framework was partly funded by a grant from The Perl Foundation.
RE2 is a software library for regular expressions via a finite-state machine using automata theory, in contrast to almost all other regular expression libraries, which use backtracking implementations. It provides a C++ interface.
LuaJIT is a tracing just-in-time compiler for the Lua programming language. Mike Pall, a primary maintainer of the project had resigned in 2015, resorting only to occasional patching to the future 2.1 version.
