Cookie has a value when it should not

I've been working on a bit of bot mitigation and began using checks against Cookie.CFID to verify the client has a value in reply.

I'm using CF  9,0,1,274733

application.cfm includes the following:

<cfapplication sessionManagement="True" clientManagement ="False" setClientCookies="True" sessionTimeout="#CreateTimeSpan(0, 0, 2, 0)#">

I disable cookies in FF 23 browser to simulate a bot and conduct the test.

In my test the check for Cookie.CFID is as expected, empty.  Here is a snippet of code used to test this.

<cftry>

    <cfif REFind("YourIPAddress",CGI.REMOTE_ADDR)>

        <cfif ! IsDefined("Cookie.cfid")>

            <cfoutput>

                No Cookies as expected!

            </cfoutput>

        </cfif>

        <cfdump var="#Cookie#">

    </cfif>

    <cfcatch type="Any">

        <cfdump var="#cfcatch#">

    </cfcatch>

</cftry>

And the result expected from that test:

No Cookies as expected! 

struct [empty]

However, with the same test environment configuration as above in another page I'm getting a non empty struct when dumping cookies like this:

<cfdump var="#Cookie#">

produces:

Is there some function or feature in ColdFusion known to cause this behavior or is this a bug?
