What's a "variable in the link"? An additional parameter?

URL's support this by appending a

Whoever receives the request must inspect the query parameters and use them as appropriate.

So, what I understand is that this value isn't available on page load, is something you want to add on 'click', right?

So for that, kust handle the link click event and do the request by hand, which should resemble something like:
<a href="" onclick="return processClick()" target="_blank">
<img src="" alt="StepsImage" />

Open in new window

var myVariable = "abcd";

function processClick(){
    var url = this.href;
    url = url + "?var=" + myVariable; 
    window.location.href = url;
    return false;

Open in new window
