sample cgi?

[Kee Nethery]

Never got an answer to this question so I figure I should perhaps ask it again.

Does someone have the standard sample cgi in Revolution that returns 
a web page that displays all the parameters that the browser sends to 
the server?

In HyperTalk the stack script that catches all the data from the web 
server via AppleEvents is shown below. The HandleOrder script takes 
some of the data and parses it and creates an HTML reply.

These two scripts are the complete cycle for a HyperCard based cgi.

Can someone show me a Revolution example? I'm hoping that the 
Revolution example also deals with cookies but a simple example sans 
cookies would be better than nothing.

Thanks, Kee


on AppleEvent class, ID, sender
  -- Here is where we receive the event, pull off the relevant
  -- information, and send it off to be processed.
  --
  -- The following is a list of the MacHTTP parameters
  -- that are available, should you need to use them:
  --
  --'addr' - client address
  --'Agnt' - user agent
  --'ctyp' - content type
  --'frmu' - from user
  --'kfor' - search arguments
  --'meth' - HTTP method
  --'pass' - the user password
  --'post' - post arguments
  --'refr' - referer
  --'scnm' - script name
  --'svnm' - server name
  --'svpt' - server port
  --'user' - user name
  --

  if class & ID is "WWW‡sdoc" then
    -- this is the CGI gateway "sdoc" message. We need to check this first to
    -- distinguish it from the Finder's, other application's AppleEvents that
    -- might also be sent to HyperCard.

    -- Pull up the basic AppleEvent data. This is dummy information in
    -- our case.
    request appleEvent data -- get the direct parameter (path args)

    -- Now get the "POST" message. This is the important information s
    -- which contain all the settings from the form going to this cgi.
    request appleEvent data with keyword "post"
