I've got a CakePHP install running six different web sites, each with their own webroot. All of the base code is the same (controllers, models, etc.), just the css, images, js and so forth are split into the separate webroots (app/webroot, app/webroot_second_site, app/webroot_third_site, etc.)
My question is: Is there a way to share common resources among the webroots? So we don't have six different copies of TinyMCE and jQuery cluttering up our project, and more importantly to me, so that we can make a change in a common CSS file instead of having to copy/paste a change across six different sites' folders?
If these sites were running on a Linux box, I think it could be fairly easily accomplished with a symlink from each of the webroots to a common folder higher up in the directory tree, but we're running Windows Server 2003 / IIS 6. Any suggestions?
