A simple HTTP service to store & retrieve ephemeral data.

The application can be used to `POST`, `PUT`, and `GET` a limited amount of data.  
Old data will automatically be removed.  
You may choose to have data immediately removed once it's been retrieved.

This can be used as a simple clipboard on the web.

# Examples

Create a password on your computer and share it with your mobile device.

```sh
pwgen -s 128 1 \
    | tee my-new-password \
    | https post webclip.example.org/?once=1 \
    | jq -r .url \
    | qrencode -tUTF8
```


Share a clipboard between multiple devices.

```sh
# Choose a unique name for your clipboard.
WEBCLIP=my-private-clipboard

# Copy something on your computer, make it available to your web clipboard.
xclip -o -sel clip | https put "webclip.example.org/$WEBCLIP"

# Load something from your web clipboard.
https "webclip.example.org/$WEBCLIP" | xclip -sel clip
```

# Feature ideas

Some of these ideas might be bad, as they could impact performance or security negatively, or just aren't useful.

- Support setting the response content-type to allow sharing of rich media files
- Support query param `new=1` for `POST` & `PUT` to ensure no existing data is replaced
- Encrypt data in memory/storage
- Support long-polling for updates, effectively claiming a clipboard for `once` ops before it's created, `http "${url}?wait=1" &; <secret http put "${url}?once=1`
- Support 302 redirects, `echo 'https://example.org/my/space' | https put "$url"; http --follow "$url"`
