HttpCookieCollection.Add vs HttpCookieCollection.Set - Does the Request.Cookies collection get copied to the Response.Cookies collection?

I just want to clear this up.

I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection.

I want to update my existing Cookie.

Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection? Do I need to add a new cookie with the same key using Response.Cookies.Add(), or do I need to use Response.Cookies.Set()?

There is a difference:

Duplicate cookies typically requires extra handling to determine which is the most recent. I'm not sure of a case when you would want duplicate cookies on the same site, maybe someone else can chime in with an example

Edit: In your case, you want to use set because you are updating.

In Python, how does one catch warnings as if they were exceptions?

python exception exception-handling warnings

A third-party library (written in C) that I use in my python code is issuing warnings. I want to be able to use the try except syntax to properly handle these warnings. Is there a way to do this?
