For any site, even one that does not accommodate channels, Internet Explorer 4.0 will support a subscription. A subscription sets up an automatic download of a site on a periodic basis. A subscription is fundamentally different from a channel because the browser checks the site as opposed to the site broadcasting to the browser. This means that you can ask IE 4.0 to check a given site for new content and download at regular intervals. If the computer must use dial-up networking, a subscription can be established so that the modem is used automatically.
