Protocol Handler Interfaces

Protocol handlers are the Enterprise Search in Microsoft Office SharePoint Server 2007 components that access a content source in its native format, and expose documents and other content items to filter.

Enterprise Search supports the implementation of new protocol handlers to expand the content sources that can be crawled. Use the protocol handler interfaces, described in the following table, to implement a custom protocol handler.
