Offline Reader Pro is basically a web browser with one powerful feature, it allows you to take a snapshot of the page that you are browsing in PDF format (with all texts, images, etc) and save it for later review or continue reading when you are not online.
Great for long and bandwidth consuming articles, books or blog posts.
Offline Reader also supports custom proxies including HTTP, HTTPS, SOCKS v4 and SOCKS v5.
Enjoy.
