We are really struggling with the DNN environment and need your help.

We have DNN 7.0 and for the life of us cannot determine how to manage the variable for a visitor across the entire site. For example, we would like to create an Adwords campaign for customers who live within a 5 mile radius of our facility and to these customers we would like to display our physical street address, to the others we will not display our physical street address.

For example:
Google Adwords 5 mile campaign URL: www.GetTeck.com?address=true
Google Adwords else campaign URL: www.getteck.com?address=fase

After the user clicks on the Adwords link we want to know what the “true / false” value was while the customer remains on the site navigating among the pages.

We do not trying to place a cookie for future use, we just want to pass a URL query string in the initial URL and then be able to somehow preserve the variable – there has got to be some way to managing / maintaining data in the system? Otherwise the DNN environment is not much better than a set of static pages!

Understand that we are NOT saying we want to use session variables or cookies - we just want to do this the correct way for DNN.

Can we just query the query string and store the data in the DNN database during the users session? What should we do?
