[Zope] How to get Search engines to index dynamic pages?

*This message was transferred with a trial version of CommuniGate(tm) Pro* We have several customer sites with dynamic pages created with data from MySql. Many search engines doesn't index an URL with a query string like: Http://www.somesite.com/category_page?category=2 will be indexed as: Http://www.somesite.com/category_page Is there a method with in Zope or a Zope product that can help me create a site map with links like: Http://www.somesite.com/category_page/category/2 I know there is a tool for asp http://xde.net/xq/tool.xqasp/qx/index.htm. Something similar for Zope? I guess apache with mod_rewrite can help me but I rather do it within Zope. Tnx Joakim Nicander
