问题 I am experiencing a problem with IE caching the results of an action method. Other articles I found were related to security and the [Authorize] attribute.

Why? in view: <td> <%: Html.CheckBox("Visible") %> </td> in controller: adslService.Visible = bool.Parse(collection["Visible"]); 回答1: That's because the CheckBox helper generates an additional hidden field with the same name as the checkbox (you can see it by browsing the generated source code): <input checked="checked" id="Visible" name="Visible" type=

问题 in my asp.net mvc application i'm using the OutputCache attribute on different action method. Is possible to view the current entries on the cache related to OutputCache attribute? If i cicle on System.Web.HttpContext.Current.Cache i don't find this type of entry.
