multiple root paths with Apache

Is it at all possible to create multiple ("virtual") root paths on a single Apache installation? I have seperate folders for the different sites I am concurrently developing and would like to have each as it's own root for the site files that it contains, because I am referencing my code from the root.. ie. <a href="/blah.html"> <img src="/blah.gif"> It doesn't sound logical that you could, so if not possible, are there any alternative solutions to accomplish this? I am running Win2000. Thanks Damien du Toit New Media Programmer tel +27 21 425 9710 fax +27 21 425 9713 GENERATOR COMMUNICATIONS | BE AN ISLAND
