Connecting to remote host

[Varun Nath]

This is the VCL file am using:

Note: Host is not a valid one

vcl 4.0;
import std;
import directors;

# Default backend definition. Set this to point to your content server.
backend default {
    .host = "remote.host.com";
    .port = "80";
}

sub vcl_init {
new vdir = directors.round_robin();
vdir.add_backend(default);
}

sub vcl_recv {
    unset req.http.proxy;
    unset req.http.cookie;
    set req.http.x-host = "http://remote.host.com";
    set req.http.x-clientip = client.ip;
    set req.http.x-serverip = server.ip;
    set req.http.x-localip = local.ip;
    set req.http.x-remoteip = remote.ip;
    unset req.http.X-Forwarded-For;
    set req.http.x-forwarded-for = client.ip;
    return(pass);
}

sub vcl_backend_response {
    # Happens after we have read the response headers from the backend.
    #
    # Here you clean the response headers, removing silly Set-Cookie headers
    # and other mistakes your backend does.
}

sub vcl_deliver {
    # Happens when we have all the pieces we need, and are about to send the
    # response to the client.
}

Please let me know if I need to add something more to make the remote host
caching from localhost varnish
