Httpd is a simple HTTP daemon, serving version 1.0 of the HTTP protocol. It listens for incoming calls on a given address (default: tcp!*!80). It serves content rooted at in its name space.

The httpd program supports only the and methods of the HTTP protocol. The (default and (default of a file are determined by looking for suffixes of the file name in /services/http/http.suff.

If the requested URI begins with /magic/, httpd loads the module associated with the remaining part of the URI. Take care to configure the name space sensibly. Simple servers echo and stats are provided (see below).

Httpd has the following options:

Listen for calls on the given address, expressed using the syntax of dial (2).
Set the size of the daemon's cache to cachesize kilobytes. The default is a five megabyte cache.
Debugging information is written to the file /services/httpd/httpd.debug.

Echo is a trivial server that just returns the method, URI, any search, and the headers sent by the client.

Stats is an equally simple server that queries the cache and returns information to the user about pages stored in the cache.

More complex services can be written to httpd's private interface. The file httpd.m (in /appl/svc/httpd) defines constants and adts used by httpd. The file cgi.m defines the module which is the interface for programs called using the URI /magic/.
