How do I classify the anvil cookies?

Anvil Q&A
1

What I’m trying to do:
I am setting up a cookie banner for my app using cookie-script. It’s identified a number of different cookies from anvil:
anvil-test-cookie, anvil-session-516e5e…, anvilapp, anvilapp-shared

I’ve also found the following cookies when inspecting my site that i dont know about:
AMP_067b9b07c8,

I think I need to classify these as strictly necessary or something else and also I need to know if any of them are tracking personal information.

Hi @davidtopf2,

Here’s the rundown:

  • anvil-test-cookie: No personal information, essential, just tests whether cookies work at all
  • anvil-session-516e5e...: Associates you with the session, essential. Refers to technical information (eg which IP address), but no personal information unless you store that information in the session (eg by logging in with the Users Service) or with anvil.server.session_state.
  • anvilapp and anvilapp-shared contain the data set using the anvil.server.cookies API. (Encrypted, mind you, so it’s tamper-resistant and not visible to the user!)
  • AMP_067b9b07c8: Nothing to do with Anvil that I’m aware of! Might be to do with AMP?

Yeah, but only because he was busy with the new beta designer deployment :slight_smile:

Hi Meredydd, I’m sorry for my limited technical knowledge but could you perhaps explain what this means in a bit more detail?

Is it just for knowing which server calls came from the same browser session? Or does it associate a user who previously visited the website with the current session?

“you” is the app user I’m assuming? Or the app developer?

I was also curious if the string at the end changes for each session?

Thank you in advance!
