[Zope] Can you make an alternate folder the default?

This is probably a stupid question but once again, I haven't been able to find the answer myself. I've been doing everything in root. I don't want to have to specify the sub-folder name in the URL. Right now, they can to go http:\\EIS and it takes them to the index_html object tin the root folder. I ended up having to move everything into a subfolder in order to get the LDAP authorization working. Now I have a sub folder called EFS so to get to my application, the users need to go to http:\\EIS\EFS. Is there any way to make a sub-folder the default point for the URL? In other words, if you go to http:\\EIS\xxx can Zope look in the EFS sub-folder for xxx?
