Is there any other way to disable the caching of the page? cause i have a page where in the background image in a DIV that keep on changing for every refresh. the problem is when a post back is trigger the background image wont refresh bec. it is cache in the browser. I've tried using this commands in server side Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d); Response.Expires = -1500; Response.CacheControl = "no-cache";
