ASP.NET offers many improvements over classic ASP. The topics covered in this chapter highlight several of the major improvements in controlling, configuring, and deploying ASP.NET applications.
ASP.NET provides easy control of the entire application through the
global.asax file. This text file allows you to
create event handlers for a wide variety of events exposed by both
the application as a whole and by individual sessions. You can also
include methods and server-side include files that will apply
globally to the entire application.
Configuration of web applications is handled using the configuration
web.config. These XML files provide a flexible
and hierarchical configuration scheme. Configuration settings can
apply to every application on the web server, to specific
applications, or to specific subdirectories within an application.
Since all of the configuration and control for ASP.NET applications is done with text files, either XML or some other variant of plain text, it is very easy to maintain and update a web application remotely. It is no longer necessary to be physically present at a web server to reconfigure the application through IIS.
Perhaps the single greatest improvement that .NET has made over previous generations of development environments is in the area of deployment:
dll files only have to be located in a specific
directory to be visible to an application.
