Hi Deepa,

I had a look through the blog post and I just wanted to check you have done the following:

1. Installed the nuget package.
2. Configured it as per the readme .
3. Add the Attribute to a controller and tested '[ContentOutputCache(Duration = 86400)]'.

If this is all working then I think a good place to start looking is the order of the service registration.

From the first blog you should have added:

services.AddOutputCaching();

To then use the custom implementation of 'IOutputCacheVaryByCustomService' you would need to call the service registration after this:

services.AddTransient<IOutputCacheVaryByCustomService, OuputCacheVaryByCustomService>();

Does this all look like your code?

You can see the example startup.cs here

Yes followed all these steps as mentioned here. 

I believe no content cache will work unless you set the content cache properties in appsettings, see https://docs.developers.optimizely.com/content-management-system/docs/configuring-cms#contentoptions

E.g.

  "EPiServer": {
    "CMS": {
      "Content": {
        "VersionCacheSlidingExpiration": "0:0:10",
        "ContentCacheSlidingExpiration": "0:0:10"
      }
    }
  }

Hello,

Yes added this configuration in appsettings.json file. It will not fire the GetVaryByCustomString() method from service.

Do we need to call this method explicitly apart from adding this line [ContentOutputCache(Duration = 86400, VaryByCustom="visitorgroups")] for controller action method?

Thanks,

Deepa
