Wget Feature Specifications
This page holds feature specifications and related discussions, for possible future functionality in GNU Wget.
Note: this page is not the proper place to submit feature requests; each item here should already be tracked in the BugTracker, and should already have been confirmed (set to the "Confirmed" state) by a developer.
Even if the bug report exists and is confirmed, it is not automatically a candidate for inclusion here; this page is specifically for features that require planning and discussion to implement.
Current Generation Features
Feature specifications for Wget 1.x
RFC 2617-compliant authentication in Wget
Pipelining to other processes, to filter HTML before link-reaps, to handle link-reaping, for both HTML and non-HTML content, or translate URIs to local filenames.
Specification for when Wget should send an initial HEAD request prior to a potential GET request
Support for internationalized URIs
Automatic saving of information from a Wget session, for tracking important headers, especially Content-Type and ETag. Also maps between local filenames and the original URI, for timestamp and content-length-checking purposes
Changes to make to the way automated testing works in Wget
Next Generation Features
Feature specifications for a future, "next-generation" Wget (2.x?)
Abstract "file system" layer that handles output of downloaded items; enables support for such things as downloading-to-tarball, or to multipart/related archives, etc.
Clean up options for commandline and configuration
A way to specify arbitrary protocols for the transport layer—even arbitrary programs!
Support for keeping multiple connections open at a time
Support for associating configuration options with specific URIs
An API for developers to write their own dynamically-loaded plugins
Pipelining requests in HTTP/1.1, to speed up time between responses
Support for option and .wgetrc-names in alternative languages to English.
Allow run-time decisions through script code.
Features that will not officially be part of canonical Wget, but which will be supplied as plugins for Wget. It is expected that these will be provided as separate packages, apart from the core Wget distribution.
