Remove the cache object in Asp.Net
Data stored in the ASP.NET cache is considered volatile, meaning it is not intended for permanent storage. The cache is designed to hold data temporarily and can be removed or overwritten based on various factors such as cache expiration policies, memory limitations, or explicit cache invalidation. It serves as a high-performance storage mechanism for frequently accessed or computationally expensive data, allowing for faster retrieval and reducing the load on underlying data sources. However, it should not be relied upon as a long-term data storage solution, as its primary purpose is to improve performance and scalability of web applications.
Reasons for automatically removed from the cache
It might be automatically removed from the cache for one of these reasons:
- Because the cache is full.
- Because the item has expired.
- Because an item it is dependent on changes.
In addition to allowing items to be removed from the cache automatically , you can explicitly remove them. Cache object's Remove method can be used to remove data from the cache.
If the value in the key parameter is not found, returns null.
