Several months ago, Bill Boga and I, realized there was a performance enhancement we could make in our infrastructure. We were utilizing IdentityServer and took notice that many of our APIs were validating many of the same access tokens and storing the results in memory locally. Validating access tokens can be relatively expensive due to additional web requests and CPU intensive hash calculations. If we could cache the validation results, and share the validation results across our system, then we could reduce the work necessary to get a request through our APIs.
