Proxy URL without authentication
I have an Apache web server with basic authentication enabled at the root directory.  I can't change this due to business restrictions.

However, we want a particular URL to be a proxy to a different site, with different authentication, without being asked for authentication by the main site.

Example:
My site is http://foo.com/  
If you go to http://foo.com/ in a browser, you are presented with a typical authentication popup.

If I add this:

    ProxyPass /bar/ http://bar.com/

then I go to http://foo.com/bar/ , I am presented with an authentication popup for bar.com followed by an authentication popup for foo.com

How can I do this sort of proxy and "ignore" the authentication from the original site?
