sharing directories in virtual hosts

Hi,

I would like share some directories (called photos, images, css and js)
over several virtual hosts, so that e.g. http://virtualhost1/photos and
http://virtualhost2/photos reflect the same physical directory. I hope
you can help me....

It looked simple. In de tux document root I did:

mkdir a
mv /other/place/photos a
mv /other/place/images a
etc

and in de virtual host document roots:

cd virtualhost1
ln -s ../a/photos .
ln -s ../a/images .

Unfortunately it looks like tux does not handle symbolic links that
start with "..", neither symbolic links that start with "/".

In the documentation I saw that a security feature is that url's that
contains a forbidden substring such as ".." will not be served by Tux.
Does this have something to do with this symbolic link behaviour?

I thought a using normal links, but there are about 350 virtual sites
that should share the same directories and there thousands of file
involved. This would make a reliable management of the files difficult.

I thought about using outbound links in html
(http://photos.virtualhost1/) but there changes to the pages needed for
that.

What would be a secure way share directories over virtual hosts? 


Thanks,
Herald
