In one of my previous post I have talked about How to get list of all active HttpModules in ASP.NET? Where I have explained how we can get list of all active modules of an ASP.NET Application at runtime. In this post, I am going discussed about, how you can get details of a particular module details from list of modules.
While working with ASP.NET web application you must be familiar with one of most important state management technique “Session”. If you want to do a quick refresh or want to know some thing more, please go ahead and read one of my article “Exploring Session in ASP.NET” published at Code Project. In this post I am going to share some important tips that might be useful.
Session is one of most important state management in ASP.NET. We can enable or disabled session state either in web.config or using @Page directive’s EnableSessionState attributes. But there was no provision to change the session state at runtime till date in ASP.NET. But using ASP.NET 4.0, we can change the session state programmatically . The .NET 4.0 framework adds a new method SetSessionStateBehavior to the HttpContext class for ASP.NET. This method required SessionStatebehavior value to set the current session mode. To call SetSessionStateBehavior simply create a new HttpModule by Implementing IHttModule and hook the BeginRequest event. Most important you can only use the SetSessionStateBehavior until the AcquireRequestState event is fired, because AcquireRequestState Occurs when ASP.NET acquires the current state that is associated with the current request
While calling SetSessionStatebehavior, You can pass the following values as SessionStatebehavior :
Default: This is default setting which means everything works as before
Disabled: Turned of Session Sate for Current Request.
ReadOnly: Read only access to Session State;
Required: Enabled session state for both Read and Write Access;
