esp8266 open txt from server


I have the esp8266 connected to my computer. I have connected it to my network and it works. The problem is that I dont know how to request this document .
Command looks like so:


But I dont know what to do next, maybe a GET, but how?
I want that document to be shown in my serial monitor (using the one with arduino software) over which i speak to the esp from the computer.

Thank you

EDIT: I want to do something like this but with the esp8266
