Well, technically extensions dont matter at all. The reason it makes no diff on the server is hat the mime type for both .html and .shtml files will be returned as text/html which is what the browser pays attention too. I suspect that on your system shtml are not set to text/html mime type. If you change that, all should be well. Alternatively I suggest runnign all your files as html and configuring your server to parse the includes on html files as well.
