# -H sets the header
# -v includes the header information
# /dev/null pipes the contents of the page output into a blackhole
curl -v http://<server-host_or_ip>/ -H "Host: domain.com" > /dev/null

# Example
curl -v https://localhost/ -H "Host: www.dentalmanagers.com" > /dev/null
curl -v http://appserver-4/ -H "Host: www.1111dental.com" > /dev/null
curl -v http://appserver-4/ -H "Host: test.roadsidedentalmarketing.com" > /dev/null

# View the HTML output
curl -v https://localhost/ -H "Host: www.dentalmanagers.com" | less
