Add "Host" header to address HTTP 403 error

[JChristensen]

About a week ago, the arduino-tweet.appspot.com site started returning HTTP/1.0 403 Forbidden. Adding the HTTP "Host" header seems to fix this.

Thanks! LGTM.

Just curious, are you aware of anyone else having this issue? A friend and I both had it but I was surprised when I checked the Arduino forum, I didn't find anyone else reporting it.
Cheers!

Hello. Thank you for fixing the 403 error! I really appreciate it.

Though the tweets are now sending, I'm having an issue:

twitter.wait() is hanging for four minutes before returning the HTTP status code.

Here's a snippet of my code:

boolean sendTweet(char* hashtag, char* tag, boolean open){ 
  if(open){
    delay(500);                                                  
    strcpy(tweet, msg_OPEN);                  
    strcat(tweet, hashtag);
    strcat(tweet, msg_asOf);
    if (hour12 > 9)                                                                  
      strcat(tweet, " ");  
    strcat(tweet, timestamp);  
    strcat(tweet, tag);
  } else {
    delay(500);                                                  
    strcpy(tweet, hashtag);
    strcat(tweet, msg_asOf);
    if (hour12 > 9)
      strcat(tweet, " ");
    strcat(tweet, timestamp);
    strcat(tweet, tag);
  }
  lcd.clear();                                                                         
  if (twitter.post(tweet)) {
    Serial.println("Tweet sent");
    Serial.println("About to check twitter.wait()");
    status = twitter.wait();
    Serial.println("twitter.wait() checked");
    Serial.print("Status: ");
    Serial.println(status);

    if (status == 200) {
      lcd.print("Tweet sent!");
   Serial.println("Tweet sent");
      lcd.setCursor(0,2);                                                                        
      lcd.print(statusString);
      delay(2000);
      return 1;
    } else {
      lcd.clear();
      lcd.print("Failure! Error ");                        
      lcd.print(status);
      delay(2000);                                                                      
      strcpy(statusString, "ERROR Tweet not sent");
      lcd.setCursor(0,2);                                                                        
      lcd.print(statusString);
      lcd.setCursor(0,3);
      lcd.print("Wait 1 min ");                                  
      // one minute required by NeoCat  
      delay(60000);
      
      return 0;
    }
  } else {
    lcd.clear();
    lcd.print("Connection failed.");
    delay(2000);
    strcpy(statusString, "ERROR Tweet not sent");    
    return 0;
  }  
}

Here is the serial output:

Tweet sent
About to check twitter.wait()
twitter.wait() checked
Status: 200
Tweet sent

The time between "About to check twitter.wait()" and "twitter.wait() checked" appears to be exactly 4 minutes. Is it a problem with my code or are others experiencing this?

Thanks again,
Jeremy
