Developers love the ASP.NET application cache. One reason they love it is that ASP.NET lets them create dependencies between items placed in the cache and files in the file system. If a file targeted by a dependency changes, ASP.NET automatically removes dependent items from the cache. Combined with cache removal callbacks—notifications broadcast to interested parties when cached items are removed—cache dependencies are a boon to developers seeking to maximize performance by minimizing time-cons... |

One of the most compelling improvements that ASP.NET brought to ASP programming was the Cache object. The Cache has some similarities to the Application object and is a container of global data (as opposed to session-specific data) that features a fair number of innovative characteristics. At its core, the ASP.NET Cache is a sealed data container class built around a hashtable and defined in the System.Web.Caching namespace. The Cache object is central to the whole ASP.NET infrastructure. Variou... |

When it comes to getting the most performance out of your ASP.NET application, caching is one avenue to look into. Earlier this year I demonstrated how to use SQL Cache Dependency using SQL Server 2005 and 2008, but this time I’ll demonstrate how to cache files using ASP.NET Cache Dependency.... |

If you're developing an ASP.NET application, Web services or a high-performance computing (HPC) application, you're likely to encounter major scalability issues as you try to scale and put more load on your application. With an ASP.NET application, bottlenecks occur in two data stores. The first is the application data that resides in the database, and the other is ASP.NET session state data that is typically stored in one of three modes (InProc, StateServer, or SqlServer) provided by Microsoft.... |

Caching greatly improves application performance because it reduces expensive trips to the database. But, if you want to use caching in your application, you must decide what to cache and where to put your caching code. The answer is simple. Cache your domain objects and put caching code inside your persistence classes.... |

We often use the XmlDataSource control together with the TreeView control.
If the data source is static, it works quite well. But, when the data source needs to be dynamic, there seems to be some problems. This article will introduce one such problem and give you a hack solution.... |

One of the most sure-fire ways to improve a web application's performance is to employ caching. Caching takes some expensive operation and stores its results in a quickly accessible location. Since it's inception, ASP.NET has offered two flavors of caching:
* Output Caching - caches the entire rendered markup of an ASP.NET page or User Control for a specified duration.
* Data Caching - a API for caching objects. Using the data cache you can write code to add, remove, and retrieve i... |

The surest way to write a sluggish Web application is to perform file or database accesses on every request. Every developer knows that reading and writing memory is orders of magnitude faster than reading and writing files and databases. Yet it's surprising how many of the same developers build ASP and ASP.NET pages that hit a file or database on each and every page access.... |

Introduction: It is a way to store the frequently used data into the server memory which can be retrieved very quickly. And so provides both scalability and performance. For example if user is required to fetch the same data from database frequently then the resultant data can be stored into the server memory and later retrieved in very less time (better performance). And the same time the application can serve more page request in the same time (scalability).... |

For building scalable and high-performance Web based applications, ASP.NET provides a feature called data caching. Data caching enables programmatic storing of frequently accessed data objects in memory. This feature can be extended to vastly improve performance for ASP.NET applications that query data stored in an Oracle database. This article describes a strategy for caching Oracle database data in ASP.NET Web applications deployed using a Web Farm environment. This technique enables caching o... |

For most ASP.NET developers, the Cache (ala System.Web.Caching) offers great promise for scalability and performance, especially in a mostly read-only environment. The hardest part about caching is populating it with data. What are the safest ways to get this data? What are the safest ways to store this data? The author will discuss his framework for accessing and storing data in the ASP.NET cache (with a "Generics" twist). He also shows how to keep your cache fresh with the help of detailed exp... |

Caching is the method of saving data to some form of memory (generally computer, not yours) with the aim of speeding up the time it takes to access that data. When you access a page, your browser will cache the page on your computer so that if you pressed the back button, it wouldn't have to download the page files again.... |

The concept of Caching was introduced in ASP.NET 1.X and has been improved significantly in ASP.NET 2.0. Caching allows you to store commonly used items in the memory and thus not create them from scratch when they are requested. There are different types of Caching available in the .NET framework. In this article I will introduce you to Caching dependencies.... |

Caching is a technique of storing an in-memory copy of important and much used data/information to improve the performance of any software system. The idea is to place frequently used data in quickly accessed media. The ASP.Net runtime includes a key-value map of CLR objects called cache. This lives with the application and is available via the HttpContext and System.Web.UI.Page. Using cache is to some extent similar to using Session object. You can access items in the cache using an indexer and... |
