This module implements a web server, suitable for embedding in an
application. The server is object oriented, and contains all of the
fundamentals needed for a full service website.

[section {Minimal Example}]

Starting a web service requires starting a class of type
[cmd httpd::server], and providing that server with one or more URIs
to service, and [cmd httpd::reply] derived classes to generate them.

[example {
oo::class create ::reply.hello {
  method content {} {
    my puts "<HTML><HEAD><TITLE>IRM Dispatch Server</TITLE></HEAD><BODY>"
    my puts "<h1>Hello World!</h1>"
    my puts </BODY></HTML>
  }
}
::httpd::server create HTTPD port 8015 myaddr 127.0.0.1 doc_root ~/htdocs
HTTPD plugin dispatch httpd::server::dispatch
HTTPD uri add * /hello [list mixin reply.hello]
}]

The bare module does have facilities to hose a files from a file system. Files that end in a .tml will be substituted in the style of Tclhttpd:

[example {
<!-- hello.tml -->
[my html_header {Hello World!}]
Your Server is running.
<p>
The time is now [clock format [clock seconds]]
[my html_footer]
}]

A complete example of an httpd server is in the /examples directory of Tcllib. It also show how to dispatch URIs to other processes via SCGI and HTTP proxies.

[example {
cd ~/tcl/sandbox/tcllib
tclsh examples/httpd.tcl
}]
