CHAPTER 6 ■ DEPLOYING YOUR WEB SITE
Figure 6-11. Managing your application extensions
You can browse through the settings in this dialog box to see the handlers for each
file type. For example, the ASPX file type is handled by aspnet_isapi.dll.
Side-by-Side Execution
There are several versions of the .NET Framework available: 1.0, 1.1, 2.0, 3.0, and 3.5.
These are installed in separate directories in your primary Windows folder (the location
of which varies by operating system). You may have noticed that the Application Configuration
dialog box is a property of the virtual directory and not of the machine itself. Thus,
you can specify different versions of aspnet_isapi.dll to handle each site. Therefore, you
can configure a site in one virtual directory to use ASP.NET 2.0 and another site in a different
virtual directory to use ASP.NET 3.0.
Thus, a single web server isn’t bound to a specific version of ASP.NET.
Manually Deploying Your ASP.NET Applications
Because ASP.NET 2.0 has a runtime compilation model, deployment is a lot easier than in
previous versions of ASP.NET—for simple applications, you just deploy your ASPX and
code-behind files, and the web server handles the rest.
