Protocol H<strong>and</strong>lers<br />

Protocol h<strong>and</strong>lers are needed to make the initial connection to a content source.<br />

Protocol h<strong>and</strong>lers tell the gatherer how to connect to the target content. SharePoint<br />

Portal Server includes protocol h<strong>and</strong>lers for the following document types:<br />

■ File shares<br />

■ Web pages<br />

■ Web pages using Secure Sockets Layer (SSL)<br />

■ <strong>Microsoft</strong> Exchange Server public folders<br />

■ Lotus Notes databases<br />

Other protocol h<strong>and</strong>lers can be installed, such as an FTP protocol h<strong>and</strong>ler, that<br />

will enable the Search service to connect to a File Transfer Protocol (FTP) site as a<br />

content source. In addition, you can write your own protocol h<strong>and</strong>lers to connect to<br />

a content source by using any transport protocol you want. Please reference the<br />

SharePoint Software Development <strong>Kit</strong> (SDK) for more information.
