title: what is ServicePointManager.ServerCertificateValidationCallback
body: <p>I'm using a web service in my website. the provider provide me a sample code, in the code there is a line like this:</p>
  
  <pre><code>// For Ignore SSL Error
  ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
  </code></pre>
  
  <p>The web service link users to its own page and then return to my website. it uses <strong>https</strong>.</p>
  
  <p>What is this code application? Is it for ignoring <strong>certification error</strong> in users' web explorers?</p>
  
  <p>I think the certification with the web server's site may not be valid certification, or it's just a local certification. Am I right?</p>
  
  <p>Thanks.</p>
