is it just how it looks, or are CGI programmers a special kind of
breed who simply cannot be bothered to set up a test environ-

if I were a CGI programmer, I'd do something like this:

1) use a stub CGI script to grab some sample data from the
server and save to a file. e.g.

    # myposttarget
    import os, sys
    data = sys.stdin.read(int(os.environ['CONTENT_LENGTH']))
    file = open("/temp/data.txt", "w")
    print "Content-Type: text/html\n\nok, thanks!"

2) run the script on that sample chunk until it works.  if the
script needs more environment variables, set them in the shell:

    $ cp /temp/data.txt .
    $ ls -l data.txt
    $ -rw-r--r--    1 myself myself 11750 Oct 20  2036 data.txt
    $ export CONTENT_LENGTH=11750
    $ python myposttarget.py <data.txt

exceptions and print statement will appear in the terminal window,
as usual.

3) repeat 1-2 until it appears to work pretty well.

4) deploy.

Cheers /F
