  <p>I am trying to submit the email address for newsletter subscription. (Magento has this). </p>
  
  <p><i>Following is showing newsletter subscription form's code</i></p>
  
  <pre><code>&lt;form action="&lt;?php echo $this-&gt;getFormActionUrl() ?&gt;" method="post" id="newsletter-validate-detail"&gt;
      &lt;div class="form-subscribe"&gt;
          &lt;div class="input-box"&gt;
              &lt;input type="text" name="email" id="newsletter" title="&lt;?php echo $this-&gt;__('Sign up for our newsletter') ?&gt;" class="input-text required-entry validate-email" /&gt;
          &lt;/div&gt;
          &lt;button type="submit" title="&lt;?php echo $this-&gt;__('Go') ?&gt;" class="button"&gt;&lt;span&gt;  &lt;span&gt;&lt;?php echo $this-&gt;__('Go') ?&gt;&lt;/span&gt;&lt;/span&gt;&lt;/button&gt;
      &lt;/div&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p><code>echo $this-&gt;getFormActionUrl()</code> generate the action url with the https on it. </p>
  
  <p>example: </p>
  
  <p>following sites will have URL called <b><a href="https://www.site.eu/newsletter/subscriber/new/" rel="nofollow">https://www.site.eu/newsletter/subscriber/new/</a> </b> Because Configuration I set base secure url as <a href="https://www.site.eu/" rel="nofollow">https://www.site.eu/</a></p>
  
  <blockquote>
    <p>&nbsp;&nbsp;&nbsp;<a href="http://www.site.it/" rel="nofollow">http://www.site.it/</a><br/>
    &nbsp;&nbsp;&nbsp;<a href="http://www.site.es/" rel="nofollow">http://www.site.es/</a><br/>
    &nbsp;&nbsp;&nbsp;<a href="http://www.site.fr/" rel="nofollow">http://www.site.fr/</a><br/>
    &nbsp;&nbsp;&nbsp;<a href="http://www.site.de/" rel="nofollow">http://www.site.de/</a><br/></p>
  </blockquote>
  
  <p>Other sites will redirect to https with their own domain. These will work properly<br/>
  <a href="http://www.site.com/" rel="nofollow">http://www.site.com/</a>   Redirect to <a href="https://www.site.com/" rel="nofollow">https://www.site.com/</a><br/>
  <a href="http://www.site.co.uk/" rel="nofollow">http://www.site.co.uk/</a> Redirect to <a href="https://www.site.co.uk/" rel="nofollow">https://www.site.co.uk/</a></p>
  
  <p>If user click submit button within any of above site then the site will navigate to <a href="https://www.site.eu/newsletter/subscriber/new/" rel="nofollow">https://www.site.eu/newsletter/subscriber/new/</a> but without having any post data. So according to the situation I cannot access POST variables (email)  </p>
  
  <p>I believe I have explained the the problem properly. Please advice why is this happening? Any solutions come to your mind?</p>
