Other Links

Table 11-1 lists URL types that are not as well known or useful as mailto or ftp://, but are available. As with other links, place these URLs after the href attribute within the anchor element.

Table 11-1. Alternative link protocols

Type	Syntax	Use
File	file:// server / path	Specifies a file without indicating the protocol. This is useful for accessing files on a contained site such as a CD-ROM or kiosk application, but it is less appropriate over networks (such as the Internet).
News	news: newsgroup news: message_id	Accesses either a single message or an entire newsgroup within the Usenet news system. Some browsers do not support news URLs, so you should avoid using them.
NNTP	nntp://s erver:port / newsgroup/article	Provides a complete mechanism for accessing Usenet news articles. The article is served only to machines that are allowed to retrieve articles from this server, so this URL has limited practical use.
Telnet	telnet:// user:password@server:port /	Opens a Telnet session with a desired server. The user and password@ elements are optional and follow the same rules as described for ftp://.
Gopher	gopher:// server:port/path	Accesses a document on a gopher server. The gopher document retrieval system was eclipsed by the World Wide Web, but some gopher servers are still operating.
