How to add information to cookies

I am using Coldfusion. I have used a tool to generate a report about cookies and with some of the cookies it had information like purpose and service. How do I add extra information to my cookies?

For example:
Name:      __tlbcpv
Purpose:      Used to record the cookie consent preferences of visitors
Provider:      .termly.io
Service:      Termly View Service Privacy Policy  

Country:      United States

It sounds like you want to add custom information to the cookies.

So now a cookie has






as defined by https://tools.ietf.org/html/rfc6265#section-5.2

If you yourself want to add 

Purpose:      Used to record the cookie consent preferences of visitors

there is no current mechanism to do so.

I would suggest you use a lookup table in your tool to store the purpose

Charlie ArehartTroubleshooting Consultant
WestCoast_BC, it seema like the kind of cookie info you are referring to is about what would be shown in a "cookie policy", meant to report to users the purpose of all cookies on your site

The kind of text you quote is not coming from the cookies. Instead, it's text generated from any of various cookie policy generators. Those tools do their own lookup first of your cookies, then they generate the text based on their own  assessment of what such cookies (from generic site providers) are "about".

So your point would be how to tell such tools to regard your own site's custom cookies. There is no provision in cookies to do that.

Sound reasonable?
