The Date
general HTTP header contains the date and time at which the message was originated.
Note that Date
is listed in the forbidden header names in the fetch spec - so this code will not send Date
header:
fetch('https://httpbin.org/get', { 'headers': { 'Date': (new Date()).toUTCString() } })
Header type | General header |
