title: Difference between link and postLink in cakephp
body: <p>I am new to cakephp. Please bear with me. I want to know what is the difference between </p>
  
  <pre><code>$this-&gt;Html-&gt;link();
  </code></pre>
  
  <p>And </p>
  
  <pre><code>$this-&gt;Form-&gt;postLink();
  </code></pre>
  
  <p>As i have seen both of them will output anchor tag only. What makes the use of postLink() over link() ????</p>
