I decided to put some of the questions I get from time to time on my blog, if they involve code samples at least.

            Subject: Page Caching








                     







            I use the following markup to disable caching for specific pages in my app. 






            <%@ OutputCache Location="None" VaryByParam="None" %>







                     







            Do you know how to do this gloablly, for whole application? 







             





            Answer:






            void Application_PreSendRequestHeaders(object sender, EventArgs e)









                                        {









                            










                                            Response.ContentEncoding = System.Text.Encoding.UTF8;











                                            Response.Cache.SetCacheability(HttpCacheability.NoCache); 









                     










                                        }









                     







            Add that to the global.asax that will disable all caching







                     







            More info on the HttpCacheability object :
