g.3gl.net RPC tracking & refresh call fix

[lukemulks]

Observed RPC tracking bypassing Shields on boston.com and sfgate.com (likely Google gRPC)

Strong suspicion this is google, or from a google partner. Definite references to hawklogserver domains, but searches result in either pen testing for windows or vague google references. The absence of search results is suspect given the data passed, and behavior of the requests.

I've tested the filter rule and am able to confirm successful blocking, and no noticeable issues with Google access.

Two requests take place, which then refresh. The second request passes ad, cookie and location data from the user, which appears to pass device data as well.

This is what we're blocking:

Request URL:
https://g.3gl.net/jp/100/v2/C

Response:

function RPClient(){}
(function(){RPClient.c =100; RPClient.pu = "r.3gl.net/hawklogserver/r.p"; RPClient.r =2000; document.onConfigLoaded!==undefined&&document.onConfigLoaded();})();
