to play with cookies

this serves a nginx server on port 8443

> [!CAUTION]
> you want to change your `/etc/hosts` (on \*nix)

```
# /etc/hosts
127.0.0.1 website.com a.website.com b.website.com sub.a.website.com
```

to add attributes, modify the file `cookieattr`
```
# cookieattr
set $cookie_attr 'Secure; Domain=a.host.com; HttpOnly;';
```
note that the `;` at the end is the line terminator for nginx config and is necessary

next, install `just` for your system. take a look at <https://just.systems> if unsure how

get `podman` too while you're at it. you don't have `openssl`? what insane operating system are you on? get openssl too.

```console
$ just setup-tls
$ just container
$ # now you mess around with cookieattr
$ # you look at https://a.website.com https://b.website.com https://sub.a.website.com
$ # you can tell you need to tell your browser you want a taste of danger
$ just reload
$ # ^ do that when you make changes to server.conf
```
