[OpenLayers-Users] How to refresh the div "map" only?

Sun Aug 22 06:40:40 EDT 2010

well that depends that what do you call a refreshed map? when you will
call the init function it will obviously follow whats written in
function init(), if you firebug on mozilla firfox.. you can check the
map object for a possible reload funtion. or you might need to define
a different function.
