Effective N-Layering in ASP.NET

This presentation will focus on tools and techniques associated with the rapid development of ASP.NET applications. It will begin by introducing N-Layering basics as described in Martin Fowler book “Patterns of Enterprise Application Architecture” and it will then demonstrate the creation of an N-Layered ASP.Net application with specific focus on 3 real-world scenarios;

1.      ASP to ASP.NET migration where the client does not want the back end (Database) to change

2.      ASP.NET Spaghetti Code refactoring using the existing stored procedures

3.      ASP.NET's effective use of the ObjectDataSource or LINQ with the Microsoft Entity Framework

ASP.Net Pipeline Extensibility : Http Modules, Http Handlers, IHttpHandlerFactory, IHttpAsyncHandler and HttpApplication
By Joël Hébert

The HTTP Pipeline can be extended in ASP.NET adding pre and post processing to incoming requests. This said there are multiple scenarios that can benefit from these processings. The presentation will include a real life HttpHandler scenario based on an "Ip Address Authentication Mechanism". The HttpHandler will handle multiple scenarios via the Factory pattern and will be fired asyncronously.

The presentation is for Intermediate to Advanced ASP.Net developers interested in tapping into the pileline's end points or starting points in order to: url rewrite, serve images, authenticate and authorize requests, capture errors and more.

Attending this presentation will ensure comprehension of: ASP.Net Pipeline Extensibility Options, Http Modules, Http Handlers, HttpApplication class, Key Interfaces for handlers ( IHttpHandlerFactory & IHttpAsyncHandler)

A demo of a HttpHandler will showcase:
-How to create Http Handlers that are Asyncronous and tied to the Factory pattern
-Utilizing a custom IP Class to verify ipranges
-The SqlCacheDependency in Sql Server 2000 and 2005
-How to add Session State support in a Httphandler
