-- Every CGI script that returns any valid JSON object will work in the test.
-- In case you do not have not yet used CGI, you may want to use this script which is written in Lua.
-- You may download an interpreter from http://luabinaries.sourceforge.net/download.html, extract it
-- to some folder in your search path (the path of the webserver or /usr/bin on Linux), and add the
-- following lines to your .conf file.
