outputcache

问题 Right now I have OutCache on an action with duration set to 365 days. However depending on some events I would like to clear the cache and there are multiple conditions for clearing cache. Moreover, VaryByParam is not an option. How can I achieve this? I think I can do something like this, store a variable in cookie like: RefreshCache = false and check this in VaryByCustom override method. Incase the RefreshCache evaluates to true, reset it to false, increment VaryByCustom argument variable

问题 How is it possible to invalidate the whole output cache in asp .net mvc 2? 回答1: AFAIK this is not possible. You can only invalidate specific actions that might have been cached by decorating them with the [OutputCache] attribute. HttpResponse.RemoveOutputCacheItem(Url.Action("Index", "Products")); 回答2: While I don't know if there is a way to do it in code, still recycling the worker process might invalidate the server cache. If this is true then you might even do it in code by having code to

The problem is that Output Cache settings seem to override the Client settings. Here is what I have setup: Custom ActionFilterAttribute Class public class ClientCacheAttribute : ActionFilterAttribute { private bool

问题 I have code that is cached this way: [OutputCache(Duration="3600", Location=OutputCacheLocation.Client)] Now, I don't exactly know how this output cache works. Where exactly does it keep the copy of a page? And what are the differences between OutputCacheLocation.Client and OutputCacheLocation.Browser ? 回答1: Where exactly does it keep the copy of a page?
