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 .

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 -

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.

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
