title: Does HTTP response "200 OK" give a guarantee that the document has been received by the machine who generated the HTTP request?
body: <p>I have two machines, A and B.</p>
  
  <p>A sends an HTTP request to B and asks for some document.
  B responds back and sends the requested document and gives a 200 OK message, but machine A is complaining that the document is not received because of a network failure.</p>
  
  <p>Does HTTP code 200 also work as acknowledgment that the document is received?</p>
