title: How to write in 'mailto' body link to current page
body: <p>I have <code>mailto</code> button in all pages of my site and I want to write reference to that page in e-mail body.</p>
  
  <p>In one page I can have</p>
  
  <pre><code>&lt;a class="email" title="Email a friend" href="mailto:?subject=Interesting%20information&amp;amp;body=I thought you might find this information interesting:%20%0d%0ahttp://www.a.com/Home/SiteMap/tabid/589/Default.aspx"&gt;Email&lt;/a&gt;
  </code></pre>
  
  <p>But how can I make this generic for all pages?</p>
