手动输出缓存刷新 [英] Manual outputcache refresh

问题描述

现在，我对一个持续时间设置为365天的动作执行了OutCache.但是，根据某些事件，我想清除缓存，并且清除缓存有多种条件.而且，VaryByParam不是选项.

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.

我该如何实现?

我想我可以这样做，将变量存储在cookie中，例如:RefreshCache = false并在VaryByCustom重写方法中进行检查.如果RefreshCache评估为true，请将其重置为false，将VaryByCustom参数变量增加1.

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 by 1.

但是，我不确定这是否是实现我想要的效果的有效方法.

However, I am not sure this is an efficient method to achieve what I want.

推荐答案

您可以使用但是，这仅适用于存储在服务器上的OuputCache项目.如果要在客户端上缓存，则此方法将无效.

However, this will only apply to OuputCache items stored on the server. If you're caching on the client then this method will have no affect.

希望这会有所帮助.
