Wget Configuration for the Proxy
This article describes the GNU Wget free software package for retrieving files from the Internet.
The Wget command line tool can be used with the HTTP and HTTPS protocols. It supports HTTP proxies and can be called from scripts or scheduled jobs.
Wget runs on most UNIX-like operating systems as well as on Windows.
ProxyMesh supports configuration of the Proxy Host with Basic Authentication as well as IP address authentication. With the latter, you don't need to use a username and password.
Wget can support your use cases, making it easy to retrieve large files or mirror entire websites.
You'll find more details at http://www.gnu.org/software/wget/.
