simple check, http - function doesnt match documentation?

[pdwalker]

According to the 1.1 documentation ( http://www.zabbix.com/manual/v1.1/co...ems_simple.php ), the http simple check is of the form

http,<ip>,<port>


And yet when trying the following formats it shows up as unsupported:

http
http,<ipaddress>
http,<ipaddress>,80


However, this works:

http,80


Am I doing something wrong, or is the documentation showing something that has not been coded in yet?
