Is there a way to set a cookie for exactly 1 request?

Question

I want to set a cookie (using JavaScript or jQuery) to only be sent exactly once.

I can set a cookie with an expiry date say 1 second away just before making the request, but this seems little delicate. I was wondering if there is a way to guarantee that a cookie survives for 1 request, and only one request...

I have had a look through the docs on MDN but con't see anything that fits the bill.

Any Ideas?

Answer 1

You could use an AJAX complete handler to remove the cookie after every request.

https://api.jquery.com/ajaxComplete/

$(document).ajaxComplete(function() {
    // delete your cookie
});

Here's one way:

1. Encode the value of the cookie in JSON format, e.g.

var c = {"foo":"bar"}
Cookies.set('test',JSON.stringify(c))

2. Add to that cookie value a nonce value such as the desired expiration time of the cookie itself, e.g.

var c = {"foo":"bar","expire_time":1612561366588}
Cookies.set('test',JSON.stringify(c))

3. Expire the cookie once that time has passed, using the standard cookie deletion method on either client or server, e.g.

var c = JSON.parse(Cookies.get('test'))
if (c.expire_time < (new Date()).getTime()) {
  Cookies.remove('test')
}
