Let's say i have this controller

public class abController : BaseApiController
{
        [HttpGet]
        [Route("api/x", Name = "x1")]
        [CacheOutput(ServerTimeSpan = 3600, ClientTimeSpan = 3600)]
        public async Task<IHttpActionResult> getX([FromUri] xRequest request)
        {

        }


        [HttpGet]
        [Route("api/y", Name = "y")]
        [ActionName("y")]
        [CacheOutput(ServerTimeSpan = 3600, ClientTimeSpan = 3600)]
        public async Task<IHttpActionResult> getY([FromUri] yRequest request)
        {

        }
}

as u can see there is caching on both methods, but for method

getY

there is another controller who does POST so when POST is done i want the caching on method getY to be skipped

    public class addController: BaseApiController
{
        [HttpPost]
        [InvalidateCacheOutput("y")]
        [Route("api/y/add", Name = "add")]
        public async Task<IHttpActionResult> addY([FromUri] addYRequest request)
        {

        }
}

What I have tried:

As u can see i put action Name on the method that i want to skip the caching in it

[ActionName("y")]

and now in method addY i put

[InvalidateCacheOutput("y")]

but it's not working

i want when addY is called the caching on method getY to be skipped

It looks like you're using the Strathweb.CacheOutput library. Looking at the documentation, the value passed to InvalidateCacheOutput needs to be the method name whose cache you want to invalidate. You don't have a method called y on the addController, so the attribute does nothing.

Try:

C#

[HttpPost]
[InvalidateCacheOutput(nameof(abController.getY), typeof(abController))]
[Route("api/y/add", Name = "add")]
public async Task<IHttpActionResult> addY([FromUri] addYRequest request) ...
