<% include("http://www.com";) %>
Another (admittedly ugly) solution might be to have a4d call some ITK or 4DIC 4d code that would get the HTML for the page you want to include write the result to a file and have a4d include it.
We've developed a reasonably tidy solution between two 4D servers in a commercial project, where the content is transferred using a BLOB. For non-4D servers, we're using HTTP transfer and though it works seamlessly, the performance is poor: approximately 30% performance against a local A4D file. I wouldn't recommend it, except as a last resort.
