Get Browser Page Headers for GET or POST requests

[bogdan]

I would like to get the headers from a page loaded in the browser so that i can make a post request.
I don't see any option in BAS and i searched the forum for an answer and i don't seem to find anything.
The process is like the image attached :
load page in browser ---> save page header in a variable ---> do GET or POST request!
Any help is appreciated. Thank you !
