How can a web publisher include an object in more than one HTML document?
Often HTML documents need to have the same objects or text included on many different pages. One method of doing this is by addressing the same object from different documents. Another method is using a server-side include within a document. Here the web server recognizes documents with the extension shtm’ which are parsed by the server. The parsing of the document makes the processing time longer than for a normal HTML documents.
