What is Caching? How does it work?


Caching is the process of storing copies of files in a cache, or temporary storage location, so that they can be accessed much faster than is possible. Caching lets you reuse data previously recovered or computed efficiently.

A cache is a form of memory used to speed up access to the data. The storing of that information saves the user time by getting to it faster, and lessens the traffic on the network.

If your application has to read data it will try to get the data from the cache first. Only when it is not located in the cache should it attempt to get the data from the data store.

Dot Net Development Company also uses multiple nodes for caching, as caching have many advantages.

The data will not be available in the following cases:

  • If its lifespan out,
  • When the application has its memory released,
  • If for whatever reason caching doesn’t occur.

Advantages of Caching:

Every wearable App Development company should use caching for developing app. There are many Advantages of caching:

  • The definition of the cache can make or break your computer system output.
  • For repetitive operations, the cache takes the heavy load/execution from the server.
  • Decrease load on Web Services / Database.

Disadvantages of Caching:

Caching has some disadvantages also which are given below:

  • In terms of the Caching method, the actual data material in the delayed writings would not be coherent.
  • Maintenance strengthened
  • Lack of scalability

Caching in ASP.NET

All the software development company use cache. ASP.NET supports caching of various forms such as

In-Memory Caching:

The In-Memory Cache stores data in the Web Server memory where a web application is being hosted. You may host an application on a server farm on a single server or multiple servers. The In-Memory Cache functions well when an application is hosted on a server, so when an application runs on the server farm, we can make sure the sessions are sticky.

Data Caching:

As the name suggests, data caching is usually connected to computer applications or content management solutions (CMS) databases. This increases device performance by allowing for faster load time. When an application requests data that is stored in the database, it is extracted from the database and transmitted to the user under normal circumstances. The database can only handle so many requests at a time, however. It is where caching of the data will help. It is often used to caching data that remain unchanged or is occasionally altered in the database. Such data will be stored on local memory and delivered to the user once requests are sent in; thus, unnecessary trips back to the database are greatly reduced.

Class Caching:

Web pages or web services, when running for the first time, are compiled into a page class in assembly. The assembly is then cached in the server. The next time a request for the page or service is made; reference is made to the cached assembly. When the source code is changed the assembly is recompiled by the CLR.

Distributed caching:

A distributed cache is a cache shared by many app servers, typically operated by the app servers that access it as an external service. A distributed cache can improve the performance and scalability of an ASP.NET Core app, particularly when the app is hosted by a cloud provider or a server farm. Distributed caching is primarily used by big-timers like Google and Facebook, which have a global audience and experience a high volume of traffic. With the support of distributed caching, these companies can fulfill user requests without fail, irrespective of the geographic location of the consumer. Due to a large network of caches used in this form of caching, there is practically an infinite amount of data that can be stored and served when the user asks.

Configuration Caching:

Application wide configuration information is contained in a configuration file. Configuration caching stores information about the configuration in server memory.

Response caching:

Response caching is a page storage technique in the cache server location for a certain period of time, so instead of getting from the server whenever we can get the request from the server, the response caching is managed by header details.

Output Caching:

A copy of the finally made HTML pages or part of the pages sent to the client is stored in the output cache. Instead of regenerating the page, a cached copy of the page is submitted when the next client asks for this address, thereby saving time.

Fragment Caching:

Caching the whole page is not ideal because any section of the page is specific to the application as a whole. So Fragmentation Catching is used to caching any portion of the page, so we can use a User Control to do Fragmentation Caching.
