The MAX_FILE_SIZE item cannot specify a file size greater than the file
size that has been set in the upload_max_filesize in the PHP3.ini file
or the corresponding php3_upload_max_filesize Apache .conf directive.
The default is 2 Megabytes.
Please note that the CERN httpd seems to strip off everything
starting at the first whitespace in the content-type mime header
it gets from the client. As long as this is the case, CERN httpd
will not support the file upload feature.
