Is receiving an uploaded file the only thing your cgiprogram
should do ? I like to know if you already know how to handle
GET requests (with QUERY_STRING) and POST requests (CONTENT_LENGTH
and readig from STDIN).

For your uploaded file you read the contents from STDIN because
the REQUEST_METHOD POST is used. There are also all kinds of
headers to be read from STDIN first.

You will see things like:
     Content-Disposition: form-data; name="userfile4"; filename="e:\a2x.txt"
     Content-Type: text/plain

Sadly enough you have to check Content-Type: as the protocol/coding
is different for different types of files.

Please tell more about what you already know and show the
code where you tried to handle the upload and tell what kind of
difficulties you encountered.

Hans.
