I have a question about sitemaps that are run on dynamically generated sites.  My site [ External links are visible to forum administrators only ] is dynamically generated using .asp code.  The various page URLs are typically not friendly; that is, the URLs will not use common keyword terms. After setting the custom 404 page I then get friendly URLs that show page levels with commonly used keywords.

How do sitemaps treat these types of dynamically generated web sites?  Are they going to show unfriendly or friendly URLs?  How will google and other search engines "see" these sitemaps?

sitemap generator will "crawl" all your links similar to normal (himan) visitor, i.e. it opens homepage, finds all links on it (dynamic or se friendly link - the ones that are visible on page), then visits those pages etc, until full site is indexed.
