Webcasting is a piece of software used when you subscribe to a site. To do it, launch the browser and click on Favourites Ø Add Subscriptions

Webcasting provides to each user automatic delivery and offline access to the information and Web sites that he or she uses most often. This new "push" model of content delivery has begun a wave of new technology that will revolutionise how users receive information on the Internet.

1/2- Basic Webcasting - Webcast any existing Web site

 

Microsoft Internet Explorer 4.0 automatically enables Webcasting of any existing Web site without requiring modifications to the site. In order to Webcast content from a conventional Web site, Internet Explorer 4.0 performs a scheduled "sitecrawl" of the site content, checking for updated content and optionally downloading information for offline use. Once the user subscribes to a site, Internet Explorer 4.0 periodically checks the site for updated content and passively notifies the user of changes.

Internet Explorer will notify the user of content changes either by providing a red "gleam" on the corresponding item in the Favourites menu or by sending e-mail. If you have requested the ability to work with the information offline, Internet Explorer 4.0 will download updated content for offline use. You can then browse the site offline available without the need for an active Internet connection.

 

 

2/2- Subscribing to a Web site - the underlying technology

 

There are two flavours of Web-site subscription, depending on whether the user has chosen to download content for offline use or to only monitor for content changes.

If you customise a subscription to only check for updated content, Microsoft Internet Explorer 4.0 periodically visits the site, checks the subscribed page to see if content has changed, and notifies you if new content is available. Note that in this case no content is downloaded.

If a user wants to view subscribed content, Internet Explorer visits the site on a scheduled basis and crawls the pages, downloads only the modified pages, and notifies the user that new content is available for offline browsing.
