Reading the session storage data

Is there a way in Golang to read the session storage key/value, not the cookie? prefer using standard Golang libraries without the need to use a third party library.

Theoretically you can create a Go html template with only Javascript. This Javascript executes and send back the desired response as a fetch or similar.

So instead of “open a window” you trigger a Javascript that reads the content of the sessionStorage key/value and send it back to the server…
