Hi there does anyone know how to do this, just got some advice on my site about changing page headers but not sure how to do this (it might even be a server config)

If I were you I'd look at changing the Expires: portion of your page header response. At the moment it read 'Expires: Mon, 26 Jul 1997 05:00:00 GMT'.
If you want a browser to retreive a new copy everytime visited you should set it to '-1' rather than a backward dated timestamp.
