Setting cookies about amazon-cloudfront-developer-guide HOT 3 CLOSED

Hi @cwinters-2w - You're right, those A/B testing examples are just parsing cookies in the client request, not setting them. But yes, you should be able to set cookies with a Lambda@Edge function. The next example on that page shows how to override a response header, which gives you the general idea for setting response headers in a Lambda@Edge function. To set a cookie, your Lambda@Edge function needs to set the Set-Cookie header to the desired value, then add it to the response sent to the client. The MDN web docs explain the Set-Cookie header, if you're not familiar with it.

I'll try to set aside some time soon to add a set cookies example to the docs, and also to fix the description of the A/B testing example to make it clear that it's only reading cookies, not setting them.

I've updated the description of the A/B testing example to clarify that it's only reading cookies, not setting them. I'd still like to produce an example that shows setting them, and will leave this issue open until that's done.
