Server Side Google Analytics — utm variables

Question

So I have set up on my server a page that will be called depending on certain conditions. This script creates the .gif for google analytics and hits their server.

I've confirmed with my clients they're seeing the page hits; however, some want to see UTM variables (utm_campaign, utm_source, utm_term, etc...). I can't seem to get the UTM variables to stay, I've attached them to the tracking string but they look like they're being removed. Will this require the UTME piece?

    <cfset TrackingStringFromEDOM = ("http://www.google-analytics.com/__utm.gif?" & 
        "utmwv=4.4sh&" &
        "utmn=#RandRange(0,2000000000)#&" &
        "utmhn=#URLEncodedFormat(urlDomainString)#&" &
        "utmr=%2D&" &
        "utmp=#URLEncodedFormat(utmp)#&" &
        "utmac=#googleID#&" &
        "utmcc=__utma%3D999.999.999.999.999.1%3B&" &
        "utmvid=#id#&" &
        "utmip=127.0.0.0"
    ) />
    <cfoutput>#TrackingStringFromEDOM#</cfoutput><br/><br/>

    <cfhttp method="get" url="#TrackingStringFromEDOM#" timeout="1000" />

Answer 1

First I would write the variable a bit differently:

<cfset TrackingStringFromEDOM = "http://www.google-analytics.com/__utm.gif?" & 
        "utmwv=4.4sh&" &
        "utmn=" & RandRange(0,2000000000) & "&" &
        "utmhn=" & URLEncodedFormat(urlDomainString) & "&" &
        "utmr=%2D&" &
        "utmp=" & URLEncodedFormat(utmp) & "&" &
        "utmac=" & googleID & "&" &
        "utmcc=__utma%3D999.999.999.999.999.1%3B&" &
        "utmvid=" & id & "&" &
        "utmip=127.0.0.0"
     />

Another thing is some parameters don't seem to be in the list of the gif parameters - please check http://code.google.com/intl/en/apis/analytics/docs/tracking/gaTrackingTroubleshooting.html#gifParameters
