imgproxy Files

Added

• Add X-Origin-Width and X-Origin-Height to debug headers.
• Add IMGPROXY_COOKIE_PASSTHROUGH and IMGPROXY_COOKIE_BASE_URL configs.

Change

• dpr processing option doesn't enlarge image unless enlarge is true.
• 304 Not Modified responses includes Cache-Control, Expires, and Vary headers.
• imgproxy responds with 500 HTTP code when the source image downloading error seems temporary (timeout, server error, etc).
• When IMGPROXY_FALLBACK_IMAGE_HTTP_CODE is zero, imgproxy responds with the usual HTTP code.
• BMP support doesn't require ImageMagick.

Fix

• Fix Client Hints behavior. Width is physical size, so we should divide it by DPR value.
• Fix scale-on-load in some rare cases.
• Fix requests_total counter in Prometheus.
