If host is not supplied, http@ connects to the local host. If page is not supplied, http@ requests /. If port is not supplied, http@ uses port 80.

TCP port 80 is the well-known port for the HTTP service. Some computers respond to HTTP requests on this port. For example, they may be running tcpserver -R -H -l0 0 80 httpd /public/file/ using tcpserver(1) and httpd(1).

History

http@ was originally part of Daniel J. Bernstein's ucspi-tcp toolset in 1999.
