Many modern web browsers have a mode entitled offline browsing, where links to webpages are redirected to local copies in a temporary folder. The local copies are generally created automatically in the browser's cache and deleted automatically. Many web browsers allow the user to explicitly set specific pages to be browsed offline, which guarantees that they will not be deleted from the user's cache.
There are many different programs which follow links on a page and save all the pages reached on your hard disk. They can then be browsed after you have disconnected. One of the most popular (yet is free) is HTTrack.
By making multiple simultaneous server requests, BackStreet Browser can quickly download entire website or part of a site including HTML, graphics, Java Applets, sound and other user definable files, and saves all the files in your hard drive, either in their native format, or as a compressed ZIP file and view offline.
In addition to the embedded quick-view browser window in the main program screen, you can launch your default browser for viewing any downloaded projects.
The quick-view browser window also supports browsing zipped website, so that you don't need to unzip the files to view.
When offline, images are viewed as thumbnails or as a slide show.
Offline Navigator can download up to 100 files at a time, which saves you a huge amount of time compared to ordinary browsers.
