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.

The LWP::MediaTypes module provides functions for handling media (also known as MIME) types and encodings. The mapping from file extensions to media types is defined by the media.types file. If the ~/.media.types file exists it is used instead.

Plack::Middleware::ReverseProxy resets some HTTP headers, which are changed by reverse-proxy. You can specify the reverse proxy address and stop fake requests using enable_if directive in your app.psgi.

CatalystX::RoleApplicator applies roles to Catalyst application classes.

uWSGI presents a complete stack for networked/clustered web applications, implementing message/object passing, caching, RPC and process management. It uses the uwsgi protocol for all the networking/interprocess communications.

HTTP::Tinyish is a wrapper module for LWP, HTTP::Tiny, curl and wget.

It provides an API compatible to HTTP::Tiny.

A "public suffix" is a domain name under which Internet users can directly register own names.

Browsers and other web clients can use it to avoid privacy-leaking "supercookies", avoid privacy-leaking "super domain" certificates, domain highlighting parts of the domain in a user interface, and sorting domain lists by site.

Libpsl has built-in PSL data for fast access, allowing to load PSL data from files, checks if a given domain is a public suffix, provides immediate cookie domain verification, finds the longest public part of a given domain, finds the shortest private part of a given domain, works with international domains (UTF-8 and IDNA2008 Punycode), is thread-safe, and handles IDNA2008 UTS#46.

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.

rss-bridge generates Atom feeds for social networking websites lacking feeds. Supported websites include Facebook, Twitter, Instagram and YouTube.

Tidyp is a program that can validate your HTML, as well as modify it to be more clean and standard. tidyp does not validate HTML 5.

libtidyp is the library on which the program is based. It can be used by any other program that can interface to it. The Perl module HTML::Tidy is based on this library, allowing Perl programmers to easily validate HTML.

htmlcxx is a simple non-validating CSS1 and HTML parser for C++. Although there are several other HTML parsers available, htmlcxx has some characteristics that make it unique:

• STL like navigation of DOM tree, using excelent's tree.hh library from Kasper Peeters

• It is possible to reproduce exactly, character by character, the original document from the parse tree

• Bundled CSS parser

• Optional parsing of attributes

• C++ code that looks like C++ (not so true anymore)

• Offsets of tags/elements in the original document are stored in the nodes of the DOM tree

This module will attempt to load find and load configuration files of various types. Currently it supports YAML, JSON, XML, INI and Perl formats.

The LWP::Protocol::https module provides support for using https schemed URLs with LWP.

CGI.pm is a stable, complete and mature solution for processing and preparing HTTP requests and responses. Major features include processing form submissions, file uploads, reading and writing cookies, query string generation and manipulation, and processing and preparing HTTP headers.

This module provides a Catalyst extension to replace the development server with Starman.

This module provides a convenient way to set up a CGI environment from an HTTP::Request.

Wslay is an event-based C library for the WebSocket protocol version 13, described in RFC 6455. Besides a high-level API it provides callbacks for sending and receiving frames directly. Wslay only supports the data transfer part of WebSocket protocol and does not perform the opening handshake in HTTP.

This module allows your to run your Plack::Test tests against an external server instead of just against a local application through either mocked HTTP or a locally spawned server.

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.

This is an HTTP request parser. It takes chunks of text as received and returns a hint as to what is required, or returns the HTTP::Request when a complete request has been read. HTTP/1.1 chunking is supported.

This package contains support scripts called by libquvi to parse media stream properties.

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

The HTTP::Date module provides functions that deal with date formats used by the HTTP protocol (and then some more).

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.
