note 15415 added to function.fopen

when using fopen to open another webpage/file. is there anyway to set the HTTP_REFERER value. sample: http://www.domain.com/file.txt but the www.domain.com only accepts files to be opened from it's own server. and i would like to open the file from another server. so by setting the HTTP_REFERER to : http://www.domain.com/index.html it would belive that this file is beeing opened with the correct referer. and is alowed access. solutions, or could this be a future feature in php 4.0.7 ? http://www.php.net/manual/en/function.fopen.php
