My client asked me that a website that is hosted in one server (and pointing there through a domain) should also be accessed (into a specific directory) from another domain, which is not pointing there. For example:

http://www.foo.com, hosted at GoDaddy, with the full website

http://www.bar.com, hosted at Bluehost, needs to access http://www.foo.com/bar, as if it was the http://www.bar.com's root.

So, if anybody enters through http://www.bar.com, it should internally load http://www.foo.com/bar, without visually changing the url.

I amb not sure if this is possible using .htaccess or anything like this. Could anybody show me some light? Thanks in advance
