/**
|
|
* CSRF double-submit cookie utility.
|
|
*
|
|
* Reads the `oxicloud_csrf` cookie (which is NOT HttpOnly) and provides
|
|
* its value as the `X-CSRF-Token` header on mutating requests.
|
|
*
|
|
* Usage:
|
|
* // In any fetch call that changes state:
|
|
* fetch(url, { method: 'POST', headers: { ...getCsrfHeaders(), 'Content-Type': 'application/json' } })
|
|
*
|
|
* The server-side `csrf_middleware` validates that the header value matches
|
|
* the cookie for every POST/PUT/DELETE/PATCH request authenticated via
|
|
* HttpOnly cookies.
