After releasing the post about FLV Flash video streaming with ASP.NET 2.0, IIS and HTTP handler I have received a couple of requests on how-to run the handler on ASP.NET v1.1, so I decided to "downgrade" the solution and the code to match compatibility with the "old" framework version. All you need is to install on your IIS 5.0/6.0 the following HTTP handler and to get this to work correctly, you will need to make sure that IIS handles request for .flv files. In your site's properties, click the "Home directory tab" and click the "Configuration" button.
