Missing HttpOnly Attribute in Session Cookie

I was just given a security scan result for one of our web apps that showed two problems:

1. Missing HttpOnly Attribute in Session Cookie
2. Missing Secure Attribute in Encrypted Session (SSL) Cookie

The interesting thing is that I have both client and domain cookies set to "No" in my Application.cfm file (this is an old application that uses CF8.  Maybe I don't understand the concept?

I found a piece of code that's supposed to secure cookies:

<cfif NOT IsDefined("cookie.cfid") OR NOT IsDefined("cookie.cftoken") OR cookie.cftoken IS NOT session.CFToken>    <cfheader name="Set-Cookie" value="CFID=#session.CFID#;path=/;HTTPOnly">    <cfheader name="Set-Cookie" value="CFTOKEN=#session.CFTOKEN#;path=/;HTTPOnly"> </cfif>

But I get session.cfid and session.cftoken undefined errors.  Before I wrack my brain on something I obviously don't get, can someone steer me in the right direction?

Thanks in advance!
