I didn't say this is a bug. I said I confirmed the behavior. It's not clear to me that this is a bug because this behavior depends on how apache resolves the URL to an internal filename. I suspect that possibly a "Directory" directive in apache on the Alias directory might allow subdirectories in the Alias to be accessed as a FastCGIExternalServer path, but I can't verify that right now. Maybe on Tuesday. In other words, this may be a normal feature of apache to disallow access to files outside the approved namespaces.
