Prefetching is the process of using idle modem time to download pages into the Webcelerator cache before you click on them. Webcelerator will analyze the page you are viewing and prefetch links you are likely to follow. When you choose a link, it may load quickly from the Webcelerator cache, instead of sluggishly from the Internet. The longer you read the page, the more links are cached.

We do not have Prefetching "ON" by default so that those who pay their Internet Service Provider for the number of web pages downloaded aren't surprised by huge bills. If you pay a fixed monthly fee or pay by the hour, we highly recommend using Prefetching.

• On sites where clicking a link does more than just fetch a page (such as on-line shopping), Webcelerator's Prefetching may trigger some unexpected actions. If you are having problems with interactive sites (such as e-mail sites, online ordering, chat rooms, and sites with complex forms) you may wish to disable Prefetching.
• If you are experiencing slowdowns in other Internet programs (such as e-mail clients, FTP, and online gaming) you may find your speed returns if you disable Prefetching.
• If certain sites present Prefetching problems you can deal with them individually in the Exclude.txt file.
