I am a newbie in Nginx. I want to fetch a particular value "en" from this form data in Nginx ($request_body) "csrfmiddlewaretoken=7cV8XPsznWBtKRDw2surXEYoUU6f4Bow4JHwdzrVWOEle0J1rw35PIYmqAVBIk52&next=/&language=en".
Can this be done in Nginx.? If so, how can I write a rule in Nginx for the same one? Please support me.
