+The request cache vs. the PositionOptions cache is confusing to the reader, to explain:
+
+Testing uses mochitest httpd, so the network cache must be disabled in order for requests
+to propagate to mochitest httpd. Otherwise, every request looks like a geoip request,
+and the network request cache sees no reason to make a web request for location for geoip
+if it has already made geoip (or better) requests.
+
+We should investigate providing fake wifi and cell scans to the
+network location provider, then the network cache does not need to be shut off
+AND it will get testing coverage.
