A server-centric approach is disclosed for enabling a browser to handle content types that it cannot inherently process. Rather than executing plug-ins on a client, pluglets are executed on one or more servers. A pluglet can perform any function that a plug-in can perform. Because a pluglet resides and executes on a server, the shortcomings of the plug-in approach are overcome. Specifically, a client no longer needs to have large amounts of storage and processing resources since pluglets do not run on clients. Also, a user no longer needs to install plug-ins on a client. In addition, maintenance of the overall system is greatly simplified. To replace, add, or remove functionality, all that needs to be done is to replace, add, or remove pluglets from a relatively small number of servers. It is no longer necessary to maintain plug-ins on a relatively large number of clients. Thus, the server-centric approach enables the benefits of plug-in technology to be realized, but does so without suffering the associated shortcomings.
