+These tests exercise different ways to fetch a resource (image, font-face, svg
+references), generated via the sub-resource python script in
+```./generic/subresource/``` (for example, loading an image:
+```/common/security-features/subresource/image.py?id=<UUID>```) and later verify
+the headers used to fetch the resource.
+
+Since there is no way to wait for a resource referenced from CSS to be loaded,
+all tests use ```step_timeout()``` to delay the verification step until
+after the resource (hopefully) was loaded.
+
+Since there is also no way to retrieve headers (or other information) from
+resources loaded via CSS, we store the headers with the given ```UUID``` as key
+on the server, and retrieve them later via an XHR, for example:
+```/common/security-features/subresource/image.py?id=<UUID>&report-headers```.
