Direct domains allow you to write a page that processes a GET, takes a bunch of &foo=bar options, and spits out some computed response.

In local.tcl:

======
namespace eval ::woo {
    proc /woo {r args} {
        return [Http Ok $r [<p> "Woo! [armour $args]"]]
    }

    proc / {r args} {
        return [Http Ok $r [<p> "You said [armour $args]"]]
    }
}
======

in site.config:

======
# define the /woo URL prefix
/woo {
    domain Direct        ;# prefix handled as a Direct domain
    namespace ::woo        ;# Direct should look in ::woo namespace for functions
}
======

results:

======
http://localhost:8080/woo/?moop=1
==> You said moop 1

http://localhost:8080/woo/woo?moop=1
==> Woo! moop 1

http://localhost:8080/woo/woo?foo=bar&woo=woo
==> Woo! foo bar woo woo

http://localhost:8080/woo/woo?foo=bar&woo=woo&foo=baz
==> Woo! foo bar foo,1 baz woo woo

http://localhost:8080/woo/woo?fnurgle
==> Woo! fnurgle {}
======
