A Web component, sometimes called a WebBot, is a dynamic object on a Web page that is evaluated and executed when a page is saved or, in some cases, opened in a Web browser. The Date and Time component and the Table of Contents for This Web Site component are examples of FrontPage Web components. By using Web Components in Microsoft FrontPage, you can add a wide variety of features to your Web site, ranging from hit counters that register the number of visitors to a page, to photo galleries that display a collection of graphics. You can choose from two types of Web components: author-time components or browse-time components. Author-time components are tools that can make it easier to create and design Web pages. They are available in FrontPage. If you want to add an author-time component to your site such as a photo gallery or link bar you do not need to install specific software or a specific server technology on the Web server that hosts your site. Browse-time components are available on Web sites located on Web servers running FrontPage Server Extensions from Microsoft, SharePoint Team Services from Microsoft, or Microsoft Windows SharePoint Services.
