+Tests the Cache-control: stale-while-revalidate response directive.
+
+Purpose is to check we DON'T perform the background revalidation when we make the
+request past the reval window.
+
+* Make request #1.
+  - response is from the server and version=1
+  - max-age=1, stale-while-revalidate=1
+* Switch version of the data on the server.
+* Make request #2 in 3 seconds (entry should be expired by that time and no longer
+  fall into the reval window.)
+  - response is from the server, version=2
+* Done.
