Intelligent Server Software
Simple model:
- Server receives request for resource
- Server delivers resource to client
More sophisticated model:
- Server receives request for resource
- Server processes header information from client
- Server delivers resource to client based on client information
This is referred to as browser-sniffing or user-agent negotiation
Note that server support is now available in Apache and in server add-ons such as PHP/FI and MS Active Server Pages (ASP)
