Not sure if I follow, but if it does what I think it does, you can use VirtualDocumentRoot for that :) http://httpd.apache.org/docs/2.0/vhosts/mass.html

So instead of having to define multiple <VirtualHost> for each project I wanted a way to use dynamically have subdomains. I found a reference (see conversation link) for doing this, but it only handled one directory deep. So every project file would have to be either under one directory. What this does is is map the url to the dir:

url: experimental.someproject.somecompany.42foo.com
dir: /Users/Ryan/Projects/somecompany/someproject/experimental

url: release.anotherproject.anothercompany.42foo.com
dir: /Users/Ryan/Projects/anothercompany/anotherproject/release

I might have to try this myself, as I'm always adding new VirtualHosts for projects.

Change Log:

Added redirect for missing favicons so as to not pollute the log.

Change Log:

Added a beginning slash due to issues with some javascript files not loading.
