Resumen
The article focuses limitations of client-side approach in electronic mail-based teaching and delivery of course content. This client-side approach is only one part of a comprehensive electronic mail (e-mail) solution, which also includes server-side processing. This column addresses problems inherent in a client-only approach and describes how a server-side approach can solve these problems and provide additional functionality. The two main problems associated with client-side processing are that client needs to be active all the time and the approach causes increased network traffic. Also the problem with client-side processing is that it only occurs when the client is active. These problems can be solved through the use of server-side processing. In particular, the server-side should handle automatic document retrieval and email forwarding. It should be noted that server-side processing is not a substitute for client-side processing, but rather complements it. Both approaches, working together, lead to a more useful and powerful system. Using server-side processing for automatic document retrieval reduces the amount of email traffic and does not require a running client.
