The Static::Simple plugin is designed to make serving static content in your application during development quick and easy, without requiring a single line of code from you. This plugin detects static files by looking at the file extension in the URL (such as .css or .png or .js). The plugin uses the lightweight MIME::Types module to map file extensions to IANA-registered MIME types, and will serve your static files with the correct MIME type directly to the browser, without being processed through Catalyst.

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 the core jetty server artifact.

Nginx ("engine X") is a high-performance web and reverse proxy server created by Igor Sysoev. It can be used both as a stand-alone web server and as a proxy to reduce the load on back-end HTTP or mail servers.

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.

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.

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).

This module is a Catalyst view class for the Template Toolkit.

Objects of the HTML::Parser class will recognize markup and separate it from plain text (alias data content) in HTML documents. As different kinds of markup and text are recognized, the corresponding event handlers are invoked.

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.

This NGINX module allows adding, setting, or clearing any output or input header specified.

This is an enhanced version of the standard headers module because it provides more utilities like resetting or clearing "builtin headers" like Content-Type, Content-Length, and Server.

It also allows you to specify an optional HTTP status code criteria using the -s option and an optional content type criteria using the -t option while modifying the output headers with the more_set_headers and more_clear_headers directives.

libRocket is a C++ user interface package based on the HTML and CSS standards. libRocket uses the open standards XHTML1.0 and CSS2.0 (while borrowing features from HTML5 and CSS3), and extends them with features suited towards real-time applications. It is designed as a complete solution for any project's interface needs:

• Dynamic layout system.

• Efficient application-wide styling, with a custom-built templating engine.

• Fully featured control set: buttons, sliders, drop-downs, etc.

• Runtime visual debugging suite.

• Easily integrated and extensible with Python or Lua scripting.

Websockify translates WebSockets traffic to normal socket traffic. Websockify accepts the WebSockets handshake, parses it, and then begins forwarding traffic between the client and the target in both directions.

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

Krona is a flexible tool for exploring the relative proportions of hierarchical data, such as metagenomic classifications, using a radial, space-filling display. It is implemented using HTML5 and JavaScript, allowing charts to be explored locally or served over the Internet, requiring only a current version of any major web browser.

jq is like sed for JSON data – you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. It is written in portable C. jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you'd expect.

liboauth is a collection of C functions implementing the OAuth API. liboauth provides functions to escape and encode strings according to OAuth specifications and offers high-level functionality built on top to sign requests or verify signatures using either NSS or OpenSSL for calculating the hash/signatures.

This package provides an interactive TUI to explor the jq command line utility. The command accepts an optional query argument which will be executed against the input JSON or newline-delimited JSON (NDJSON).

This module is a Moose::Role which allows you more flexibility in your application's deployment configurations when deployed behind a proxy. Using this module, the request base ($c->req->base) is replaced with the contents of the X-Request-Base header.

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.

The WWW::RobotRules module parses /robots.txt files as specified in "A Standard for Robot Exclusion", at <http://www.robotstxt.org/wc/norobots.html>. Webmasters can use the /robots.txt file to forbid conforming robots from accessing parts of their web site.

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 the core jetty security infrastructure

Perl module Web::Scraper is a toolkit for traversing and scraping sites, inspired by Ruby's Scapi.

Tidy is a console application which corrects and cleans up HTML and XML documents by fixing markup errors and upgrading legacy code to modern standards.

Tidy also provides libtidy, a C static and dynamic library that developers can integrate into their applications to make use of the functions of Tidy.

gojq is an Go implementation and library of the jq JSON processor.
