imgproxy can use the `Width`, `Viewport-Width` or `DPR` HTTP headers to determine default width and DPR options using Client Hints. This feature is disabled by default and can be enabled by the following option:
* `IMGPROXY_ENABLE_CLIENT_HINTS`: enables Client Hints support when the width is ommited for automatic responsive images . Read [here](https://developers.google.com/web/updates/2015/09/automating-resource-selection-with-client-hints) details about Client Hints.

**Warning**: Headers cannot be signed. This means that an attacker can bypass your CDN cache by changing the `Width`, `Viewport-Width` or `DPR` HTTP headers. Have this in mind when configuring your production caching setup.
