title: how to set up request body with httpWebRequest
body: <p>I want using httpWebRequest to "POST" data to a website. So i used firebug analyzing what really send to server. First step, i use browser to browsing www.mytargetURL.net, second, turn on firebug, after that, i fill all form data and click the submit button (it's mean POST data to the server). So, I watching firebug and there was a lot of Parameters in request body part. Something like:</p>
  
  <pre><code>param1=
  param2=
  param3=default_value1
  param4=default_value2
  param5=value_I_set_byhand1
  param6=value_I_set_byhand2
  </code></pre>
  
  <p>The question is: I should set up the request body of httpWebRequest obj with all the parameters i saw in firebug parameter table (it's mean all 6 parameters) or just parameters which has value (parameter 3-6) or just parameters i have filled in the submit form(just param5 and param6)?</p>
  
  <p>Thanks you for all supports</p>
