If mod_perl is enabled on the proxy you can simply add something to=20
$r->headers_in prior to the response phase. It will be transmitted to the=20

Otherwise if you have mod_headers you can use the RequestHeader directive. =
SSL enabled vhost sets a custom header to one value the other vhost to=20
another. You must set it in both cases or someone can send that header to t=
proxy and it will be forwarded to the backend.
