title: Get the post method payload in asp.net webforms
body: <p>I need to get the payload sent by the post method in an asp.net webform. I have a <code>login.aspx</code> page called by another site as the post method like this:</p>
  <pre><code>https://example.com/Login/Login.aspx
  </code></pre>
  <p>How can I get the value of <code>SAMLResponse</code> from the payload? I've tried both of the below:</p>
  <pre><code>Request[&quot;SAMLResponse&quot;] 
  Request.Form[&quot;SAMLResponse&quot;]  
  </code></pre>
  <p>Any help is really appreciated.</p>
