go--webring provides a simple webring implementation as used by the Fediring.

Catalyst is a modern framework for making web applications. It is designed to make it easy to manage the various tasks you need to do to run an application on the web, either by doing them itself, or by letting you "plug in" existing Perl modules that do what you need.

The HTTP::Negotiate module provides a complete implementation of the HTTP content negotiation algorithm specified in draft-ietf-http-v11-spec-00.ps chapter 12. Content negotiation allows for the selection of a preferred content representation based upon attributes of the negotiable variants and the value of the various Accept* header fields in the request.

gmnisrv is a simple Gemini protocol server written in C.

Catalyst::Plugin::Authorization::Roles provides role-based authorization for Catalyst based on Catalyst::Plugin::Authentication.

Net::Server is an extensible, generic Perl server engine. It attempts to be a generic server as in Net::Daemon and NetServer::Generic. It includes with it the ability to run as an inetd process (Net::Server::INET), a single connection server (Net::Server or Net::Server::Single), a forking server (Net::Server::Fork), a preforking server which maintains a constant number of preforked children (Net::Server::PreForkSimple), or as a managed preforking server which maintains the number of children based on server load (Net::Server::PreFork). In all but the inetd type, the server provides the ability to connect to one or to multiple server ports.

The esbuild tool provides a unified bundler, transpiler and minifier. It packages up JavaScript and TypeScript code, along with JSON and other data, for distribution on the web.

HTTP::Lite is a stand-alone lightweight HTTP/1.1 implementation for perl. It is intended for use in situations where it is desirable to install the minimal number of modules to achieve HTTP support. HTTP::Lite is ideal for CGI (or mod_perl) programs or for bundling for redistribution with larger packages where only HTTP GET and POST functionality are necessary. HTTP::Lite is compliant with the Host header, necessary for name based virtual hosting, and supports proxies. Additionally, HTTP::Lite supports a callback to allow processing of request data as it arrives.

Polipo is a small caching web proxy (web cache, HTTP proxy, and proxy server). It was primarily designed to be used by one person or a small group of people.

xinetd, a more secure replacement for inetd, listens for incoming requests over a network and launches the appropriate service for that request. Requests are made using port numbers as identifiers and xinetd usually launches another daemon to handle the request. It can be used to start services with both privileged and non-privileged port numbers.

Libwebsockets is a library that allows C programs to establish client and server WebSockets connections---a protocol layered above HTTP that allows for efficient socket-like bidirectional reliable communication channels.

Varnish is a high-performance HTTP accelerator. It acts as a caching reverse proxy and load balancer. You install it in front of any server that speaks HTTP and configure it to cache the contents through an extensive configuration language.

JSON-C implements a reference counting object model that allows you to easily construct JSON objects in C, output them as JSON-formatted strings and parse JSON-formatted strings back into the C representation of JSON objects. It aims to conform to RFC 7159.

nghttp3 is an implementation of RFC 9114 HTTP/3 mapping over QUIC and RFC 9204 QPACK in C. It does not depend on any particular QUIC transport implementation.

It implements extensions specified in RFC 9218 and RFC 9220. It supports SETTINGS_H3_DATAGRAM from RFC 9297.

It does not support server push.

The Jetty Web Server provides an HTTP server and Servlet container capable of serving static and dynamic content either from a standalone or embedded instantiation. This package provides IO-related utility classes.

HTML::TableExtract is a Perl module for extracting the content contained in tables within an HTML document, either as text or encoded element trees.

This package implements a functionality to generate a ranked addressbook from your locally available email. It can be used in MUA's like aerc or mutt by grepping the list.

Authen::SASL provides an SASL authentication framework.

The Guix Data Service stores data about GNU Guix, and provides this through a web interface. It supports listening to the guix-commits mailing list to find out about new revisions, then loads the data from these in to a PostgreSQL database.

MonsterID is a method to generate a unique monster image based upon a certain identifier (IP address, email address, whatever). It can be used to automatically provide personal avatar images in blog comments or other community services.

This distribution contains a suite of modules for representing, creating, and extracting information from HTML syntax trees.

Quark is an extremely small and simple HTTP GET/HEAD only web server for static content. TLS is not natively supported and should be provided by a TLS reverse proxy (e.g. tlstunnel, hitch or stunnel).

The POSIX locale system is used to specify both the language conventions requested by the user and the preferred character set to consume and output. The Encode::Locale module looks up the charset and encoding (called a CODESET in the locale jargon) and arranges for the Encode module to know this encoding under the name "locale". It means bytes obtained from the environment can be converted to Unicode strings by calling Encode::encode(locale => $bytes) and converted back again with Encode::decode(locale => $string).

The Apache HTTP Server Project is a collaborative software development effort aimed at creating a robust, commercial-grade, featureful, and freely-available source code implementation of an HTTP (Web) server. The project is jointly managed by a group of volunteers located around the world, using the Internet and the Web to communicate, plan, and develop the server and its related documentation.
