i doubt that that's a good indicator. HTTP_PRAGMA is an old HTTP version 1. 0 header and different browsers are likely to give you different results and might or might not use that header. i'm not sure what you want can be done reliably at all. jens On Thursday, June 27, 2002, at 01:09 , Dirk Datzert wrote:

Hi,

I found out that REQUEST['HTTP_PRAGMA'] is set to 'no-cache' if the browser refresh button is pressed.

Can anybody verify that ?
