IntroductionProxy Detector is an Android app that detects proxies in yourcellular network and tells you their impact on performance forpopular Web sites. We collect the results of these measurements tohelp understand proxy behavior worldwide, and to make suggestionsfor improvement when they negatively impact your applications. Theapp lets users know if their carrier uses a Web proxy, andcharacterizes features such as caching, content rewriting, andtraffic redirection.The study is part of a Northeastern University research studywhose purpose is to determine what devices in your cellular carrierare modifying your Web traffic (e.g., loading Web pages). You mustbe at least 18 years old to participate. We collect round triptimes, object size, and object download time for the Web sites wemeasure. We collect absolutely no personal information, and you canopt-out of measurements to any Web site you do not wish the app tovisit.NotesProxy Detector will dynamically fetch websites for testing. Pleasebe patient, as our tests take some time to complete.To measure proxies in cellular networks, we of course need youto enable cellular network data during the experiment. We havetuned our system to consume only minimal data quota.The entire experiment takes about 10 minutes, and you can exitat any time. However, if you do so, your results will beincomplete. We urge you to let the tests run to completion to helpus better understand and improve Web proxy deployments.
