# what is this?

to play with cookies

this serves a nginx server on port 8443

# how to use?

## set up dns

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

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

the nginx config has these domains hardcoded. change them too if you want

## set up tls

run `make setup-tls`

you don't have `make`? well install it.

you don't have `openssl`? what insane operating system are you on? get openssl too.


## change the cookie attributes

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

## start the server

### with compose

```console
$ docker compose up -d
$ docker compose exec cookies nginx -s reload
$ # or create a make/just target to do that
```

### with podman

```console
$ 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 config
```

# what if sth doesn't work?

might be the `:z` label in the `volumes` in `docker-compose.yml`. remove it.
e.g.
```
- ./tls:/etc/nginx/tls:ro
```
