Help to understand .Net

If you want to implement pre-processing logic before a request hits the IIS resources. For instance you would like to apply security mechanism, URL rewriting, filter something in the request, etc. ASP.NET has provided two types of interception HttpModule and HttpHandler .   The web server examines the file name extension of the requested file, and determines which ISAPI extension should handle the request. Then the request is passed to the appropriate ISAPI extension.  For Example When an .aspx page is requested it is passed to ASP.Net page handler. Then Application domain is created and after that different ASP.Net objects like Httpcontext, HttpRequest, HttpResponse. HTTPModule: -    It's just like a filter. The Modules are called before and after the handler executes . -    HTTP Modules are objects which also participate the pipeline but they work before and after the HTTP Handler does its job, and produce additional services within the pipeline -  

MVC means ? MVC stands for Model View Controller. It divides an application into 3 component roles which is based on a framework methodology. These component roles are discussed briefly as follows: Models : These component roles are used to maintain the state which is persisted inside the Database. Example: we might have a Product class that is used to represent order data from the Products table inside SQL. Views : These component roles are used to display the user interface of the application, where this UI is created off of the model data. Example: we might create an Product “Edit” view that surfaces textboxes, dropdowns and checkboxes based on the current state of a Product object. Controllers : These component roles are used for various purposes like handling end user interaction, manipulating the model, and ultimately choosing a view to render to display UI. In a MVC application, the views are used only for displaying the information whereas the contro

ViewData ViewBag TempData ViewData is used to pass data from controller to view ViewBag is also used to pass data from the controller to the respective view TempData is derived from TempDataDictionary class ViewData is a dictionary object and it is property of ControllerBase class ViewBag is Dynamic property of ControllerBase class. TempData is a dictionary object and it is property of controllerBase class. ViewData is Faster than ViewBag ViewBag is slower than ViewData -- If redirection occurs, then its value becomes null If redirection occurs, then its value becomes null TempData helps to maintain the data when we move from one controller to another controller or from one action to another action ViewData is introduced in MVC 1.0 and available in MVC 1.0 and above ViewBag is introduced in MVC 3.0 and a
