Internet Information Services (IIS) 5.0 provides several enhancements to its support for ASP-based Web development, including two new server-side redirection methods: Server.Transfer and Server.Execute. Rather than redirecting requests with a round-trip to the client, these new methods can be used to transfer requests directly to an ASP file without ever leaving the server. While this functionality doesn't replace the Response.Redirect method used by IIS 4.0, you can take advantage of it to implement better application flow control mechanisms and to handle errors more efficiently. The different redirection options are described, along with some tips and tricks for implementing them on your own site.
