URI::Fetch is a smart client for fetching HTTP pages, notably syndication feeds (RSS, Atom, and others), in an intelligent, bandwidth- and time-saving way.

This module attempts to answer, as accurately as it can, one of the nastiest technical questions there is: am I on the internet?

A host of networking and security issues make this problem very difficult. There are firewalls, proxies (both well behaved and badly behaved). We might not have DNS. We might not have a network card at all!

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.

The File::Listing module exports a single function called parse_dir(), which can be used to parse directory listings.

HTTP::Server::Simple is a simple standalone HTTP daemon with no non-core module dependencies. It can be used for building a standalone http-based UI to your existing tools.

Iocaine is an HTTP server that generates a stable endless maze of Markov-babble-filled web pages. Placed behind a heavily rate-limited reverse proxy, it becomes a ``tar pit'' for trapping aggressive web scrapers commonly used to train large language models, and poisoning the collected data.

HTTrack allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer.

HTTrack arranges the original site's relative link-structure. Simply open a page of the mirrored website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads.

HTTrack is fully configurable, and has an integrated help system.
