Describe the bug

When there's a racing condition on OutputCache, with "Locking" enabled, and the first request to hit the OutputCache middleware is cancelled by the client, the middleware resolves the second request to an empty response.

I suspect that the cancelled request ends up caching an empty response and that's the one served on the subsequent requests.

Note that it only happens with the locking feature enabled.

Expected Behavior

The OutputCache middleware should not cache the cancelled request, empty response, and the successful request should return content.

Steps To Reproduce

Minimal repo: https://github.com/FP3ixoto/OutputCacheIssue

Exceptions (if any)

No response

.NET Version
