Uhttpmock is a project for mocking web service APIs which use HTTP or HTTPS. It provides a library, libuhttpmock, which implements recording and playback of HTTP request/response traces.

Jansson is a C library for encoding, decoding and manipulating JSON data.

HTML::Tidy is an HTML checker in a handy dandy object. It's meant as a replacement for HTML::Lint, which is written in Perl but is not nearly as capable as HTML::Tidy.

WebSocket++ is a C++ library that can be used to implement WebSocket functionality. The goals of the project are to provide a WebSocket implementation that is simple, portable, flexible, lightweight, low level, and high performance.

Signpost is the easy and intuitive solution for signing HTTP messages on the Java platform in conformance with the OAuth Core 1.0a standard. Signpost follows a modular and flexible design, allowing you to combine it with different HTTP messaging layers.

gmid is a fast Gemini server written with security in mind. It has features such as:

• reload the running configuration without interruption

• automatic redirect/error pages

• IRI support (RFC3987)

• reverse proxying

• CGI and FastCGI support

• virtual hosts

• location rules

• event-based asynchronous I/O model

• low memory footprint.

YAJL is a small event-driven (SAX-style) JSON parser and validating generator written in ANSI C.

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).

SSL support for Net::SMTP.

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 utility classes.

This is a parser for HTTP messages written in C. It parses both requests and responses. The parser is designed to be used in high-performance HTTP applications. It does not make any syscalls nor allocations, it does not buffer data, it can be interrupted at anytime. Depending on your architecture, it only requires about 40 bytes of data per message stream (in a web server that is per connection).

Ikiwiki is a wiki compiler, capable of generating a static set of web pages, but also incorporating dynamic features like a web based editor and commenting.

Gemget is a command line downloader for the Gemini protocol. It works well with streams and can print headers for debugging as well.

nghttp2 implements the Hypertext Transfer Protocol, version 2 (HTTP/2).

A reusable C library provides the HTTP/2 framing layer, with several tools built on top of it:

• nghttp, a command-line HTTP/2 client. It exposes many advanced and low-level aspects of the protocol and is useful for debugging.

• nghttpd, a fast, multi-threaded HTTP/2 static web server that serves files from a local directory.

• nghttpx, a fast, multi-threaded HTTP/2 reverse proxy that can be deployed in front of existing web servers that don't support HTTP/2. Both nghttpd and nghttpx can fall back to HTTP/1.1 for backwards compatibility with clients that don't speak HTTP/2.

• h2load for benchmarking (only!) your own HTTP/2 servers.

• HTTP/2 uses a header compression method called HPACK. nghttp2 provides a HPACK encoder and decoder as part of its public API.

• deflatehd converts JSON data or HTTP/1-style header fields to compressed JSON header blocks.

• inflatehd converts such compressed headers back to JSON pairs.

Feed::Find implements feed auto-discovery for finding syndication feeds, given a URI. It will discover the following feed formats: RSS 0.91, RSS 1.0, RSS 2.0, Atom.

CGI::Session provides modular session management system across HTTP requests.

IO::Socket::SSL makes using SSL/TLS much easier by wrapping the necessary functionality into the familiar IO::Socket interface and providing secure defaults whenever possible. This way existing applications can be made SSL-aware without much effort, at least if you do blocking I/O and don't use select or poll.

The Kiwix library provides the Kiwix software suite core. It contains the code shared by all Kiwix ports.

The Catalyst-Devel distribution includes a variety of modules useful for the development of Catalyst applications, but not required to run them. Catalyst-Devel includes the Catalyst::Helper system, which autogenerates scripts and tests; Module::Install::Catalyst, a Module::Install extension for Catalyst; and requirements for a variety of development-related modules.

This nginx module parses the Accept-Language field in HTTP headers and chooses the most suitable locale for the user from the list of locales supported at your website.

Gophernicus is a Gopher protocol server. Its features include:

• written with security in mind;

• automatically generated Gopher menus;

• gophertags for virtually renaming directories;

• personal gopherspaces, located in ~/public_gopher/;

• virtual hosting;

• CGI support;

• output filtering and PHP support;

• charset support and conversions;

• selector rewriting;

• session tracking and statistics;

• TLS/SSL and proxy support.

This module sets the body in redirect response, if it's not already set.

Siege is a multi-threaded HTTP/FTP load tester and benchmarking utility. It can stress test a single URL with a user defined number of simulated users, or it can read many URLs into memory and stress them simultaneously. The program reports the total number of hits recorded, bytes transferred, response time, concurrency, and return status.

Vger is a Gemini protocol server that supports chroots, virtualhosts, CGI, default language choice, redirections and MIME-type detection. It delegates TLS support to an external daemon, for example stunnel on inetd.
