Need Help Setting a Custom Referrer that Shows Up in Google Analytics

I'm trying to send a website visit through VB and use a custom referrer which will show up in Google Analytics. I've tried setting referrers on all types of webrequests: WebClient, HTTP WebRequest and WebBrowser..

I have no problems setting the referrer in the code, but the visits never show up in Analytics. I thought the WebBrowser control would definitely load the Google javascript and register the hit with the referrer, but it doesn't. Does anyone know why? Any help would be appreciated. At this point I don't really care what type of request it is, as long as it registers in Google Analytics with a custom referrer..

Thanks in advance!
