A persistent cache for ASP.NET Core

Posted on by Mahmoud Al-Qudsi

One of the nicest things about ASP.NET Core is the availability of certain singleton models that greatly simplify some very common developer needs. Given that (depending on who you ask) one of the two hardest problems in computing is caching1, it’s extremely helpful that ASP.NET Core ships with several models for caching data, chief of which are IMemoryCache and IDistributedCache, added to an ASP.NET Core application via dependency injection and then available to both the framework and the application itself. Although these two expose almost identical APIs, they differ rather significantly in semantics.2

  2. It is extremely refreshing to see Microsoft adopting the Haskell/Rust approach of using types to express/convey intention and semantics rather than merely shape. ↩

Caching and Why We Need It

Ever since the creation of interpreted languages and the birth of dynamic web content, developers have been on the lookout for tools, workarounds, and extensions in search of a solution for a solution to bring maximum performance to the world of dynamically-generated web pages.

Perhaps the simplest, most straight-forward, and most effective of these solutions is the caching technique. In most caching implementations, the dynamic content generated by user requests to a particular URI on a server trigger the caching mechanism which then stores the generated content in a "storage facility" somewhere. Future requests to the same URI retrieve the stored content rather than spend time and effort re-creating the response.

The most-popular method of caching involves the archiving of the complete HTML response generated by the webserver and then stored as a static content on the hard drive for retrieval at a later date (usually with some mechanism responsible for expiring the content upon certain actions or after a set amount of time).
