How to redirect to a url
<p>I would like to show client another page after data has been collected from previous page. But I have trouble redirect the new URL on the server side. Here is my logic:</p>

<ol>
<li>submit user input with POST action to server;</li>
<li>server run function saveChoice() to save user input into a database;</li>
<li>After user input is saved, server send a new URL to client;</li>
<li>By the time the client GET the new URL, server reads the database and get saved data out</li>
</ol>

<p>And I am stuck on step 3 (here is an example of the flow):</p>

<pre><code>type Stuff struct{
    List []string
}

func checkcheck(w http.ResponseWriter, r *http.Request) {
    sinfo := Stuff{
        List: some_slice
    }

    t, err := template.New("").Parse(tpl_ds)
    checkErr(err)
    err = r.ParseForm()
    checkErr(err)
    err = t.Execute(w, sinfo)
    checkErr(err)

    if r.Method == "POST" {
        saveChoice(r.Form["choices"])
        /* step 3: make user open another URL */
    }
}
</code></pre>

<p>And here is the template:</p>

<pre><code>&lt;html&gt;
&lt;script&gt;
  $(function () {
    $('form').on('submit', function (e) {
      e.preventDefault();
      $.ajax({
        type: 'post',
        data: $('form').serialize(),
      });
    });
  });
&lt;/script&gt;
&lt;body&gt;
  &lt;form method="POST"&gt;
    {{range .List}}
        &lt;input type="checkbox" name="choices" value="{{.}}"&gt; &lt;span&gt;{{.}}&lt;/span&gt;&lt;br&gt;
    {{end}}
    &lt;input type="submit" value="Submit"&gt;
  &lt;/form&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>May I know how I can redirect to a new page?</p>

<p>p.s. If I put URL on button, then server is not going to run saveChoice()</p>
