ESP and Ethernet Shield interface

Hello guys
in the beginning, i am a beginner in programming, in case my question is silly
I have Aruduino UNO + ESP8266 and Arduino Uno + Ethernet Shield.
ESP8266 is connected to my home WIFI Router, and Ethernet is connected to the same router with LAN cable.
i can establish a web server on both, control them without any problems through web browser.
what i need, is to send data from Ethernet shield to be received by ESP and vice versa ( i.e: the two Arduinos are communicating with each other , through ESP and Ethernet shield).

Type of data is simple : just some int. values.

can you guide me how to do that ? any links will be helpful ?

Thanks in advance

any help ?

"i.e: the two Arduinos are communicating with each other , through ESP and Ethernet shield"

I think in the past I've run both client and server code at the same time with my ethernet board. You might look at that approach for simple bidirectional communication between the two. I haven' tried it with my ESP wifi board, but should work the same.
