The check_command for a host or service definition is a reference to a
command{} definitions command_name, not the direct command line that is
run. You either need to hard-code your '-a foo:bar' to the actual
command{} definition itself like 

define command{
        command_name    check_http
        command_line    $USER1$/check_http $HOSTADDRESS$ -t 45 -a
foo:bar
        }

Or pass it as an argument from your service{} definition to a properly
configured command{} definition like

define command{
        command_name    check_http
        command_line    $USER1$/check_http $HOSTADDRESS$ -t 45 -a $ARG1$
        }

define service{
        use                             generic-service
        host_name                       somehost
        service_description             MY_HTTP_CHECK
        retry_check_interval            3
        contact_groups                  whoever
        check_command                   check_http!foo:bar
        }

In the above example, 'foo:bar' becomes $ARG1$ and is substituted into
the command_line for the command_name check_http.
