title: How to send data using POST method from ASP page to PHP page
body: <p>I have few asp controls (textboxes and checkboxes) on my asp.NET page. There is also a submit button that sends them back to me.</p>
  
  <p>I can't use clear html form (without asp controls) because I want to validate data before sending it to the outside server (js validation wouldn't be enough in this case).</p>
  
  <p>Is there any way and place (eg. OnClick button event) to programically create POST data packet and send it to an outside php page?</p>
  
  <p>Thanks.</p>
