Understanding Section Handlers - App.config File

This article explains configuration section handlers defined in the System.Configuration namespace and explains how to create custom sections handlers by implemeting the IConfigurationSectionHandler interface.
HTTP Modules
One of ASP.NET's most useful features is the extensibility of the HTTP pipeline, the path that data takes between client and server. You can use them to extend your ASP.NET applications by adding pre- and post-processing to each HTTP request coming into your application. For example, if you wanted custom authentication facilities for your application, the best technique would be to intercept the request when it comes in and process the request in a custom HTTP module.

Scramble Your Query Strings
Query strings are a very convenient way of passing information to a new window or to a following page. The problem with query strings is that the information is visible. In my experience, the wiseass users see the query strings in the browser and try to duplicate the functionality: like "Oh, when I click the button, I get 'DeleteInventory.aspx?item=123&user=george&id=99' so, if I want to delete the item #222, I just need to use 'DeleteInventory.aspx?item=222&user=george&id=99' right?" Wrong, the id=99 is the database ID for the item to be removed. The rest of the information is for populating the label controls on the page. To avoid this problem, either use POST instead of GET (made much easier in ASP.NET 2.0) or scramble the information in the querystring. Nobody will make a mess with 'DeleteInventory.aspx?value=lkajhskjhsdfoiuhrt8974325lkjh'.
