<form action="demo2.php" method="POST" id="uploadform" enctype="multipart/form-data" onsubmit="start_progres_bar()">
<input type="file" name="abc" maxlength="10" accept="gif|jpg"/>
<input name="UPLOAD_IDENTIFIER" id="uploadIdentifier" type="hidden" value="<?php echo $uuid ?>" />
<input type="submit" value="wyslij"/>
</form>

skrypt php

<?php
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

?>
