What Is the Opposite Of "Caching"?

2 minutes read

The opposite of caching, which involves temporarily storing data in order to speed up future retrieval, would be uncaching or fetching - the act of retrieving data directly from the original source rather than from a cached copy. This process typically takes longer because it requires requesting the data again from the source rather than accessing it instantaneously from a cache.


What is caching in database?

Caching in database refers to the process of temporarily storing frequently accessed data in memory to improve the performance of the system. By keeping this data in cache memory, repeated requests for the same data can be served more quickly without having to access the database, which can reduce response times and improve overall system efficiency. This can help to reduce the load on the database and improve the speed of queries and other operations.


What is caching in website optimization?

Caching in website optimization refers to the process of storing copies of files, images, and other data on a user's device or on a server closer to the user's location. By caching frequently accessed data, websites can load faster, reduce server load, and improve overall performance. This helps to decrease page load times and improve the overall user experience on a website. Different types of caching include browser caching, server-side caching, and content delivery network (CDN) caching.


How to disable caching in PHP?

To disable caching in PHP, you can add the following code to the beginning of your PHP script:

1
2
3

header("Cache-Control: no-cache, no-store, must-revalidate"); // HTTP 1.1.
header("Pragma: no-cache"); // HTTP 1.0.
header("Expires: 0"); // Proxies.


This code will set the appropriate headers in the HTTP response to instruct the browser and any intermediate caches not to cache the content. This way, the browser will always request the latest version of the PHP script from the server.
