URI Routing and Google Adwords

[eluser]Adrian Walls[/eluser]
I know this question has been asked a thousand times on the CI forums but I can't get any of the solutions to work for me. Basically I am re-building a website which has links to it from Google AdWords. Google Adwords appended

Code:

?glcid=

to the end of the URL.

My issue is that I am using CI routing from which I cannot get access to the glci parameter via GET. My routes.php file looks like:

Code:

$route['adwords-landing-page']  = "campaigns/google_adwords";

However after the routing has taken place the query string entry added by the Adwords re-direct has been removed. Is there something I should be doing in my routing to ensure the query string parameters are maintained?

Thanks in advance,
Adrian.

Just wanted to highlight this again to see if anyone has any ideas.

you have to enable query strins otherwise you can't track it right...
