title: has Http 1.0 something which I must pay attention? (php, generating requests)
body: <p>The topic is a bit strange, let me express myself.
  I used this method to generate post requests:</p>
  
  <p><a href="http://www.jonasjohn.de/snippets/php/post-request.htm" rel="nofollow">http://www.jonasjohn.de/snippets/php/post-request.htm</a></p>
  
  <p>thats ok, but after a size, I realized the datas gets changes a little, there are unwanted white spaces. Only in case of a bigger size, + a "chunked" flag appeared.
  I change the Http/1.1 protocol to Http/1.0 and now the transfers look good!
  But is there any backward, pitfalls?</p>
