WebAssistant - Proxy Offline Browser
The WebAssistant archives all web pages you have visited online. Offline too each page is available with its URL. There is no difference between browsing the internet and browsing the archive. You can even use your bookmarks and favorites list offline without any changes. When online the proxy updates your cached web pages and adds new pages automatically. This feature distinguishes the utility from most other offline browsers.
