问题
I have the following caching attribute on my controller method:
[CacheOutput(ClientTimeSpan = 14400, ServerTimeSpan = 14400)]
I am attempting to clear the cache. However, after running this line of code:
//clear cache
cache.RemoveStartsWith(Configuration.CacheOutputConfiguration().MakeBaseCachekey("BeamsController", "Get"));
I am still getting a 304 not-modified response without the controller method being invoked.
I am using this library https://github.com/filipw/AspNetWebApi-OutputCache
回答1:
[InvalidateCacheOutput("Get", typeof(BeamsController))]
seems to work, instead of 'manual invalidation' (RemoveStartsWith), above.
In fact, after reading the source code of the attribute, it appears that the documentation is wrong and it should be:
cache.RemoveStartsWith(Configuration.CacheOutputConfiguration().MakeBaseCachekey("Beams", "Get"));
which works as expected, calling the method.
