Writing CGI programs with Moscow ML		  mosml/examples/cgi/README
-----------------------------------

This directory contains two examples of using Moscow ML for writing
CGI scripts:

  1. A simple HTML form and the corresponding CGI program; 
     see README1

  2. Form-based file upload and the corresponding CGI program; 
     see README2

Moreover, there is a script which displays all the data passed to the
CGI script by the webserver.  It does so by formatting an HTML
document containing the data, and returning it to the invoking browser
for display.  That CGI program is called testcgi.sml.

WARNING: A CGI program is a program which runs on your server at the
request of a remote user, and with input supplied by that user.

Hence, regardless whether the CGI program is written in ML, Scheme,
Perl, C, or COBOL, you should:

 * beware that the permissions of the CGI programs are suitably
   restricted; (these are usually controlled by the setup of httpd,
   the webserver)
 * consider what resources remote users may consume (cpu time,
   computer memory, disk space, net bandwidth, ...)
 * never leave experimental and half-baked CGI programs lying around
   in publicly accessible cgi-bin directories, as they may have
   security holes.

Use Mosmlcgi at your own risk.  While we believe that ML, with static
type checking and automatic memory management, is a superior tool for
writing CGI programs, we accept no responsibility for problems caused
by the use of this software.
