title: Can't adjust buffer to fit data
body: <p>I am trying to make an HTTP request the with EtherCard library, then get the full response. Using the code from the examples, I'm only able to capture the headers, which are then abruptly cut off. The issue seems to be that I can't make the buffer big enough to store the data, but the data, hence why it's cut off. But it's only 292 bytes.</p>
  
  <p>Here is another question I asked trying to understand what the example code was doing: <a href="https://stackoverflow.com/questions/41617239/what-is-happening-in-this-c-arduino-code?noredirect=1#comment70436955_41617239">What is happening in this C/Arduino code?</a></p>
  
  <p>Here is the data I'm trying to GET: <a href="http://jsonplaceholder.typicode.com/posts/1" rel="nofollow noreferrer">http://jsonplaceholder.typicode.com/posts/1</a></p>
  
  <pre><code>String response;
  byte Ethernet::buffer[800];  // if i raise this to 1000, response will be blank
  
  static void response_handler (byte status, word off, word len) {
    Serial.println("Response:");
    Ethernet::buffer[off + 400] = 0;  // if i raise 400 much higher, response will be blank
    response = String((char*) Ethernet::buffer + off);
    Serial.println(response);
  }
  </code></pre>
  
  <p>See the comments above for what I've attempted.</p>
  
  <p>Here is the output from the code above:</p>
  
  <pre class="lang-none prettyprint-override"><code>Response:

  <p>As you can see, it's not the complete data, only some of the headers.</p>
