I'm running a geo-ip web cache system.

Assuming I have a domain configured, DNS replies with a different IP, depending on who asks (i.e. location in US would get a address, location in Europe would get a address, and so on).

Now, I'd like to monitor if each of the caches replies with correct content (i.e. a given page contains a given string).

Can I somehow make curl connect to a given remote IP and fetch a given vhost?

I'm thinking in something in the line of:

curl --remote-ip
curl --remote-ip

Is something like this possible with curl? I checked the manual, but I didn't find an option which would be similar in functionality.

I may have misunderstood your request, and assumed you wanted to modify the IP-address of the client (and by that its geographical location) to make the server present a certain content. If you want to connect to a different server (i.e. the DNS directs you to a different IP-address based on who asks, as you wrote), I guess you could just connect using the required IP-addresses instead of the host name curl <options> or curl <options>
Have fun using cURL!
