[Solved] Identity Server 4 caching not working issue

Share |

 

Hey guys, I've gone through some of the issue created on IdentityServer4 which were closed without proper solution.

"Issue: Identity Server 4 Caching is not working"

In simple words, it works like charm. If you know how the DI works then you even get this issue.

Here's a simple solution:

Make sure you add the below 4 store caching API at the end of identity store configurations.

What's the cause: If the cache DI is added before any other configuration then the Cache DI would be overwritten with the new DI.

.AddInMemoryCaching()

                .AddClientStoreCache<ClientStore>()

                .AddResourceStoreCache<ResourceStore>()

                .AddConfigurationStoreCache()

                .AddCorsPolicyCache<CorsPolicyService>();

Complete solutions:

Hope this solves your issue.
