Server Side Include Question

I have made a site that uses many SSI's. It all works fine however now the client needs to present the site without an Internet connection. They want to use Dreamweaver and use a local browser to go through the site. All the links are absolutes since that is the way I understand you need to make SSI links. Is there anyway that I can make the links relative and thus be able to do the presentation.
