How to connect Arduino UNO, ESP8266 to a Subdomain website using AT commands?

Its working with ThingSpeak,

AT+CIPMUX=1
AT+CIPSTART=1,"TCP","api.thingspeak.com",80
AT+CIPSEND=1,62
GET /update?api_key=myapikey&field1=123&field2=456
AT+CIPCLOSE=1

Now, I need to post a String data to a subdomain website using ESP8266, Arduino UNO Example:
https://subdomain.pythonanywhere.com

How to upload ESP8266 content to subdomain.pythonanywhere.com in 3 Steps

FOLLOW CAREFULLY

Step1:- ThingHTTP APP for subdomain.pythonanywhere.com

Step2:- change settings.py in pythonanywhere.com to avoid {%csrf_token%} error because ThingHTTP is using POST method

Step3:- AT commands

AT+CIPMUX=1
AT+CIPSTART=1,"TCP","api.thingspeak.com",80
AT+CIPSEND=1,76
GET /apps/thinghttp/send_request?api_key=YOUR_API_KEY&busid=ABC123&nfc=ABDE3456
AT+CIPCLOSE=1
