Hai All, My issue is when I am try to make a FEED in ATOM format it wont redirect (Windows Firefox only , In all other including MAC Firefox too its working). (I used feedcreator.class.php for creating feeds ) . In the case of Atom the standard content type is “application/atom+xml†and all other feeds including RSS it would be “application/xml†I am giving the header code also below..Its not redirecting in the case of ATOM (firfox windows only ..all other cases its working fine) Header("Content-Type: ".$this->contentType."; charset=".$this->encoding); Header("Content-Disposition: inline; filename=".basename($filename)); readfile($filename, "r"); Might be your suggestion would be a great help for me .. Wishing you all a nice time … Prasanth . Nair.
