It supports connecting through a proxy if either the environment variable HTTP_PROXY or http_proxy is defined. Also, downloads can be resumed like wget, in case the download is abruptly terminated. If .md5 checksums are available, they will also be downloaded and verified using ruby's digest/md5.

A test helper that makes it simple to test HTTP interaction

The attempt library provides a thin wrapper for the typical begin/rescue/sleep/retry dance. Use this in order to robustly handle blocks of code that could briefly flake out, such as an http or database connection, where it's often better to try again after a brief period rather than fail immediately.

This gem provides bindings to the Win32 SSPI libraries, primarily to support Negotiate (i.e. SPNEGO, NTLM) authentication with a proxy server. Enough support is implemented to provide the necessary support for the authentication. A module is also provided which overrides Net::HTTP and adds support for Negotiate authentication to it. This implies that open-uri automatically gets support for it, as long as the http_proxy environment variable is set.
