Several ways to disable page caching

How to disable page caching.

1. HTML prohibits page caching, just add it to the header.

2, method in asp

response.buffer = true
response.expiresabsolute = now() - 1
response.expires = 0
response.cachecontrol = "no-cache"
response.addheader "pragma", "no-cache"

3, page caching is disabled in php.

header('expires: mon, 26 jul 1997 05:00:00 gmt');
header('last-modified: ' . gmdate('d, d m y h:i:s ') . 'gmt');
header('cache-control: no-cache, must-revalidate');
header('pragma: no-cache');
?>

Another simplest method is to use ?mt=any data when using ajax.
