Can I use a Query String to drive personalized content in Sitecore 7.5? - sitecore

Question

I'm trying to display personalized content on a page IF I have clicked on a specific link on a specific page. My thought was to have a parameter on the link such as:
Go to product page
Then, on "Product Page", hopefully using the rules engine, check if the parameter home exists in the query string. If so, then display a piece of content.
I can't seem to figure out the best way to do this with Sitecore 7.5. Maybe this is the wrong approach.

Answer 1

Out of the box in Sitecore 7.5 there is no rule for using the querystring.
but you can easily create a rule and use with the personalize feature from Sitecore.
See http://blog.martinmiles.net/post/rules-engine-and-sitecore-personalization-based-on-url-query-string-parameters

Answer 2

so you would have to have something like this:
public ActionResult Index(string name)
{
Student student = new Student();
student.Name = "John";
if (!String.IsNullOrEmpty(Request.QueryString["name"]))
{
student.Name = Request.QueryString["name"];
}
return View(student);
}
For this example, my controller is named Test. So if I want to call this method I would do ~/test/index, if I do that the student object will contain the name John, however if I do ~/test/index?name=Denis , I will send an object with the name Denis
Here the name will only change when we pass the query string "name" with a value.
