i have a bunch of apache servers behind a IIS, each server have one site running and the subdomain redirect from IIS to Apache is working fine with URL rewriter + ARR, like below:
-----
a.company.com >> |IIS| >> apache_server_a (10.0.0.1)
-----
-----
b.company.com >> |IIS| >> apache_server_b (10.0.0.2)
-----
-----
c.company.com >> |IIS| >> apache_server_b (10.0.0.3)
-----
But one of my apaches have 5 client sites, he use virtual host. How i can redirect the request that IIS receive for those five sites to Apache without changing the URL?
client1.com -----
client2.com >> |IIS| >> apache_with_virtual_hosts (10.0.0.4)
client3.com -----
client4.com
client5.com
Obs:. IIS does not stay on same machine that apache servers
