Check if httponly cookie exists in Javascript

Question

As the question says can you find out if a cookie exists within Javascript if it is a HttpOnly? I don\'t need to access the information inside of it, just know it has one.

Answer 1

I had the same problem. I solved it with the server setting another cookie, not httponly, every time it refreshed the httponly session cookie, with the same max-age and no sensitive data. Now, if one of them is present, the same goes for the other, and the client can know if the httponly counterpart is there.
