You can certainly do that without specifying the HTTP "Host" parameter. However, by doing that, the health-check sent by F5 might be served by a different vHost in end-server. To put it short, it depends on vHost config in end-servers and how the listeners are configured.

You can emulate the health-check from F5 with cURL or WGET. This should give you a hint whether you can get this health-check working without touching the vHost configs in end-servers.

Test with Host header specified: 

curl -vH "Host:www.mydomain.com" http://end-server-ip:port/cpqserver/api/status

Test without Host header:

curl -v http://end-server-ip:port/cpqserver/api/status
