body: <p>Let's say I am on <code>www.example.com/?par1=test</code> and I have a Link like: <code>&lt;a href="/subpage"&gt;Link text&lt;/a&gt;</code>.</p>
  
  <p>How to pass the GET Variable to the subpage, without reading every Parameter e.G. <code>$_GET["par1"]</code> and pass it to the Link by hand.</p>
