Library for simple http communication with webserver. Library does not block work of your program (no delay() is used!), does not use memory-expensive String lib and handles most of ESP8266 errors by itself. Just set handlers, connect to AP and play with it. Ideal for JSON based applications (tested with ArduinoJson library).
Library has internal static buffer for async data recive from ESP8266. You will need to set size of this buffer according to your needs (but keep in mind that only http header can be longer than 300 characters).
Bug reports and push request are welcomed :)
Based on work by Stan Lee(Lizq@iteadstudio.com).

Library was developed with ESP8266 firmware v0.20. Older versions of firmware might not work with this lib.
After some tests it looks like there's some problems with Software Serial (and alternatives) and ESP8266, so I strongly reccomend connecting ESP8266 to Hardware Serial (if you have UNO you will need FTDI for debug).
UNO connection example, LM317T is used as voltage regulator in this case. FTDI connectior included.
MEGA connection example, LM317T is used as voltage regulator in this case.
How to connect to PC and update (firmware is included in lib files) your ESP8266 is explained in this video:

For best performance you will need connect not only 3.3V, GND, TX and RX, but also RST pin on your ESP8266. It is not required.
Header file (.h) needs to be edited according to your hardware specs. If you have UNO board uncomment "define UNO" (board with only one hardware serial). In case you are using MEGA board uncomment "define MEGA" line. Also setup desired buffer size.
Take a look at example sketch included in this lib. Yes, using this lib is that simple.
