Run the check_http as defined in the command definition, appending the
-v argument.  You'll get to see what the check_http command is
executing.  I suspect your command definition is incorrect, and you're
missing something that is supposed to be triggering the "host" header.

Where is your define command?

Hrm... this is odd, looks like you are posting the right host entry
(would still like to see the command definition).  The host entry for
"seth", is the address defined the same as the IP you are getting when
you telnet to the name? ie:

define host {
  host_name   seth
  address        10.1.1.23
}
