Hi Frans, What Chameleon does it add a random parameter to the URL (i.e. image src), eg &dummy=0.78874300+1130325893.
Also, it has a wrapper around the map image called drawmap.php which sets the pragma no cache for the header (so for the image only). I don't know of any options to do this without such an approach.

Is this possible somehow? I know it is possible to set "pragma: no-cache" in the HTML headers but that is not what I want, only the map image should not be cached. I also know it is possible to set "pragma: no-cache" in the image header, this would seem a better idea. Is this possible to achieve? Regards, Frans
