I'm using Apache 2.2
I've created 2 Virtual sub hosts.
I want one to be used for my live www and the other for internal testing, so I call it test.
DocumentRoot for www = /usr/local/apache/htdocs/w
DocumentRoot for the test site = /usr/local/apache/htdocs/t
Ideally I'd like to have the test site identical to the live site except for files I add to it or change.
If under the test site, for example, I use Alias /images/ /usr/local/apache/htdocs/w
then when I access http://testsite/images/
all my live site images come up fine. But now what I want to do is create a system where is I put an actual directory under test ...ie /usr/local/apache/htdocs/t
... I want files in that directory to be used if they're present. So I can change a file in the test environment and see it from that site without having to duplicate the entire site or directories.
