Caching in web applications
Caching is a technique that allows us to store frequently used data in memory. Instead of querying the database multiple times to get the same content, we often use caching to store this content and then retrieve it from the memory the next time we request the same content.
Caching is essential to improve performance in ASP.NET Core and the overall user experience of the product. In ASP.NET Core, there are different techniques to cache data. Here is an overview of these techniques:
- In-memory caching: In this technique, the memory of the server is used to store the data.
- Distributed caching: This technique is used when our app is deployed to Azure or when it is hosted on a farm environment. The cache is distributed across the servers contributing to this farm.
Let's learn how to implement caching in ASP.NET Core.
