ESP 8266 WebServer JSON

I programmed to ESP8266 as webserver. I send JSON-data to control some outputs. After that the ESP8266 shoult send back JSON-data to the avaible client.

I have testet the 2 Connection sepperatly. It work. When i will use a server with an client it doesnt work.

The problem is the missing client int the ESP8266 libary. In the ethernet libary its works.

Have anybody an idea or a correct libary?

with ESP8266WebServer library you do not use Client. you respond in 'on' handlers
