Rotating Favicon.icon

[kingram]

Hope the topic will fit in this category.

It might be odd but I was thinking to make the favicon.icon in the address bar to change. So hopefully I made a couple of icons and put them in the folder and used the images rotator to rotate the images and left the rotator.php in the header of the index.html

Now the favicon rotates in the Firefox each time I restart the firefox and do not rotate in IE. Here is the question obviously: what should I do that each time everyone refreshes the page in Firefox can have a new favicon. The Answer might be very simple for some coder out there but I do not know how I should clear the cache.

Thanks for help

I still can not get it rotating. It some times rotate by chance and I do not know how to go around with the problem. Any suggestion.

In the rotator.php code, add the lines shown in red below (these lines add headers that will prevent your image from being cached):

 

if ($img!=null) {

$imageInfo = pathinfo($img);

$contentType = 'Content-type: '.$extList[ $imageInfo['extension'] ];

header ($contentType);

header ("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1

header ("Expires: Fri, 05 Jul 2002, 05:00:00 GMT"); // date in the past

readfile($img);

} else {

if ( function_exists('imagecreate') ) {

header ("Content-type: image/png");

header ("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1

header ("Expires: Fri, 05 Jul 2002, 05:00:00 GMT"); // date in the past

$im = @imagecreate (100, 100)

or die ("Cannot initialize new GD image stream");

$background_color = imagecolorallocate ($im, 255, 255, 255);

$text_color = imagecolorallocate ($im, 0,0,0);

imagestring ($im, 2, 5, 5, "IMAGE ERROR", $text_color);

imagepng ($im);

imagedestroy($im);

}

}
