Is there an example of integrating a custom authentication provider that only sends http response headers? The provider does not have an API to use so I'm trying to find a way to inspect the http headers, auto-link, and store certain bits of data. The authentication is CAC/PIV based (Akamai service) and the Umbraco version is 14.1.1. https://cdn.discordapp.com/attachments/1281261113354223717/1281261114046415030/akamai_technologies-logo.png?ex=66db12e6&is=66d9c166&hm=20d7cdef73addd7b779580d1c1706f673701c202cab156f4c0d6a89f999ef8c9&
