What is Redis? Redis Cache Implementation Using .NET. Posted by Morgan Hillon 30. Each time we authenticated [or implicitly renew authorization] a user, we want to derive their authorization for controlling access in your app. A previous version of this tutorial was written by Justin Ellingwood. Redis comes with native data structures and many options to manipulate and interact with your data. Redis is an open source, BSD licensed, advanced key-value store. Cache items can be stored and retrieved by using the StringSet and StringGet methods. Redis has mostly taken over from memcached as the defacto cache for modern web applications. It is often referred to as a data structure server, since the keys can contain strings, hashes, lists, sets and sorted sets. Keeping a map of who is interested in updates to what data is a common task in systems. Redis stores most data as Redis strings, but these strings can contain many types of data, including serialized binary data, which can be used when storing .NET objects in the cache. We might consider sending the full list of authorisations [packaged with a nonce and expiry then signed of course] to the user and having them send it to you with each action as proof of authorization.
