Yes it is indeed possible. You just need to "scramble" the options a little:

 curl --header "Host: www.mysite.com" http://10.10.10.5

This makes a HTTP request to 10.10.10.5 and replaces the otherwise internally
generated "Host:" header with one of your own choice. The Host: header is
what tells the server which (virtual) server you want.
