Embedded image memory limit section-52f7c69ed8a341ceabf92ceee19b0f36

If the device has a limit on the size of images that can be embedded on a web page, image size is restricted to that size as long as the response format is jpg. The proxy limits responses to 500MB if the device does not have any limit.

Backend processing section-bdf7c294b6824de9969c97fc1f8aa6d3

The proxy downloads, verifies, and loads the Device Atlas data file once a day. The verification pulls out different properties for different devices and compares them with expected values before accepting the new data.
