WiFly.read() and buffer overflows

Hi Folks,
I have a simple loop read the WiFly output of a web client GET request response. I've seen the exact code in many examples and yet, I get buffer overflows every time. In fact, it seems the overflow is always after 61 characters (though the WiFly returns ASCII codes). I'm using a Pro Mini 3.3/8MHz. Is there some way I can handle the returned data fast enough to prevent this? DO I need to build some delay into the loop to prevent dropping out of the loop prematurely?

 char ch; 
 while (wiFlySerial.available()) {
   ch = wiFlySerial.read();
    Serial.print(ch);
  }
  Serial.println();
  
   if (wiFlySerial.overflow())
   Serial.println("response overflowed buffer");

I get the same result when I use the even more commonly used code:

 while (wiFlySerial.available()) {
   Serial.print(wiFlySerial.read());
  }
  Serial.println();
  
   if (wiFlySerial.overflow())
   Serial.println("response overflowed buffer");

Sure. Stop trying to print the data as you read it.

You need to do the exact opposite. Get rid of the delay that you have (the print to the serial port).
