I'm only guessing here, but this seems familiar, so I think it is possible
that Apache 2 introduced this behaviour.

    I doubt that if that behaviour was introduced in Apache 2, it is
possible to
    disable by a configuration directive. Sorry.

Surely there must be more reliable ways to detect whether to generate the
form or process submitted data. You could possibly use POST method on the
form and check the environment variable REQUEST_METHOD to determine which
side of the script to use. I usually 'generate the form' unless a certain
query parameter is set to a certain value (hidden field in the generated
form), in which case I process the data.

The above suggestions might be a bit off, as I don't clearly see how you are
using this script. If so, please give a bit more detail on how the script
(form generating variant) is invoked (I don't understand why your script
would generate a form if ARGC is 1).
