title: How do I post my user name and password to a web page?
body: <p>I want to post my user and password with Perl to a website. The source of the login page is:</p>
  
  <pre><code>&lt;div class="top"&gt;Sign In&lt;/div&gt;
      &lt;div class="row"&gt;&lt;label for="username"&gt;Username:&lt;/label&gt;&lt;/div&gt;
      &lt;div class="row"&gt;&lt;div id="login:usernameContainer"&gt;
          &lt;input id="login:usernameContainer:username" type="text"
          name="login:usernameContainer:username" class="username" size="16" /&gt;
      &lt;/div&gt;&lt;/div&gt;
      &lt;div class="row"&gt;&lt;label for="password"&gt;Password:&lt;/label&gt;&lt;/div&gt;
      &lt;div class="row"&gt;&lt;div id="login:j_id598"&gt;
          &lt;input id="login:j_id598:password" type="password"
          name="login:j_id598:password" value="" size="16" class="password" /&gt;
      &lt;/div&gt;&lt;/div&gt;
      &lt;div class="clearfix"&gt;
      &lt;div class="row rememberme"&gt;
          &lt;input id="login:rememberme" type="checkbox"
          name="login:rememberme" class="rememberme" /&gt;Remember Me
      &lt;/div&gt;
      &lt;div class="submit-button"&gt;
          &lt;input type="image" src="/beta/style/shun/base/base/en/text/button/button-login.gif"
          name="login:j_id603" /&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
