* KiteLib ESP8266 HTTP GET Example

*

* This example sends HTTP GET request using ESP8266 WiFi module.
|

*
|

* Please note that the response will be saved including header. HTTP header size
|
||||
* can easily exceed Arduino resources and cause the program to behave erratically.
|

*
|
||||
* IMPORTANT: Before uploading this example, make sure that the ESP8266 module is running
|
||||
* AT firmware (can be found in the /extras folder of the library)!
