- Hosts which matches ENV['no_proxy'] or ENV['NO_PROXY'] won't be proxyed.
- [,:] separated. ("ruby-lang.org:rubyist.net")
- No regexp. (give "ruby-lang.org", not "*.ruby-lang.org")
- If you want specify hot by IP address, give full address. ("192.168.1.1, 192.168.1.2")

version 2.0
- CamelCase to non_camel_case.
- SSL support (requires Ruby/OpenSSL).
- Cookies support. lib/http-access2/cookie.rb is redistributed file which is originally included in Webagent by TAKAHASHI `Maki' Masayoshi. You can download the entire package from http://www.rubycolor.org/arc/.

version J
- Ruby/1.8 support.

version H
- HTTP proxy support of version G was broken. Fixed.

version G
- Changed HTTPAccess2::Client API. Take care.
- Added streaming request API.
- Added WebDAV client sample. No XML related functions for now.
i.e, you can PUT/GET files. No PROPGET/PROPPATCH? No
versioning? Is this a DAV?

version F
- Removed dependency to delegate.rb.
Kernel.methods in delegate.rb is rather slow...
