'how easy do you need development to be?' How easy can it get?
Yes, I can switch the css easy enough, but the changes are more than just styles. And I want to test the app with real customers. I don't want them using subdirectories. What I would like is webapps/version1/ <http://www.appname.com/webapps/version1/> maps to -> www.appName.com webapps/version2/ <http://www.appname.com/version1webapps/version2/> maps to -> www.appName.com webapps/version3/ maps to -> <http://www.appname.com/version2webapps/version3/>www.appName.com<http://www.appname.com/version3> And that I could select which one goes live with a bit of xml.
