Invalidating cache in asp net

invalidating cache in asp net-34

Written by: Maria Kontorovskaya, Software Designer of Web Development Team In order to demonstrate how to use caching on a practical example, I am using a simple ASP.

When our code bases start to require continual requests to a data store, be it disk or database, that doesn't change too much overtime, caching is usually the first hammer we turn to to minimise fetching from slower stores. This is primarily because I want the content to pull from the source now and then I've used 300 seconds, but really the time may be inconsequential – I've just set it to an arbitrary number that I deemed would meet my needs. In a utility object I’m working on, tentatively called Super Cache, I’ve implemented a Clear method using the following code: An enumerator remains valid as long as the collection remains unchanged. This method would be useful if you ever just wanted to invalidate all cache entries and start fresh. When developing Web pages, performance always becomes an issue. NET MVC but the same approach can be used in any C# solution.Let’s say you have a resource that you automatically generate in your controller, but that creating that resource takes a long time…

will allow us to vary the cached result by a number of variables (host, action arguments, custom strings…) and supports timeouts etc, but it does not allow another piece of code somewhere in the application to say “that resource is not longer valid”.

It consists of the following products: And their categories: And the main task is to optimize time it takes to output all of the categories and to create a new product, because they are rarely changed and frequently used.

First, let us explore on a basic level what is cache in ASP. The concept of caching is straightforward and the following logic can be applied to any type of caching, such as HTML5 application caching and explicit caching in Java.

In order to speed up your web or cloud platform, you can use caching as one of the best practices for optimizing performance. NET and SQL Server I will show you how to implement cache without a lot of changes in the existing code. NET caching works in practice, its pros and cons, and how to make the right decision about cache selection. NET cache example in the form a simple demo project for manual method results caching and how to improve it with attribute.

In the last section, I will cover the ability of SQL Server to notify about data changes and how we can use it for cache updating.

does support this out of the box – you just don't hear about it much.
