Stateful programmatic web browsing, after Andy Lester's Perl module
The library is layered: mechanize.Browser (stateful web browser),
mechanize.UserAgent (configurable URL opener), plus urllib2 handlers.
Features include: ftp:, http: and file: URL schemes, browser history,
high-level hyperlink and HTML form support, HTTP cookies, HTTP-EQUIV and
Refresh, Referer [sic] header, robots.txt, redirections, proxies, and
Basic and Digest HTTP authentication. mechanize's response objects are
(lazily-) .seek()able and still work after .close().
