ASP URL's as Static

I have been looking for a way to change the syntax of a dynamic URL so that it appears static, to allow better access to spiders.

I have heard that you can set up your web site so that the dynamic content is contained in a server side include file. The include file can then by called by a non-dynamic page. This alleviates the problem of dynamic content not being spidered because it displays that same content on a spiderable HTML page where it can be read and indexed without any problems.

All gibberish to me! But if anybody has any snippets of code or extensions that can help I'd be extremely grateful.
