我的UA帐户已连接到以下域：http://www.mytestdomain.com，帐户ID为UA-123456-1
我没有使用analytics.js，因为此代码是通过ruby Gem从服务器触发的。
当我尝试跟踪链接域时，它运行良好：
http://www.google-analytics.com/__utm.gif?utmwv=4.4sh&utmn=7108653235&utmhn=mytestdomain.com&utmcs=UTF-8&utmul=en-us&utmdt=PAGE_VIEW_TITLE&utmhid=6413225625&utmp=4.html&utmac=UA-123465-6&utmcc=__utma%3D1.197975304100145214523.2102153242.1405604565.1405604565.15%3B%2B__utmz%3D1.1405604565.1.1.utmcsr%3D(direct)%7Cutmccn%3D(direct)%7Cutmcmd%3D(none)%3B&utmr=&utmip=
但其他领域无法跟踪：
http://www.google-analytics.com/__utm.gif?utmwv=4.4sh&utmn=7108653235&utmhn=notmydomain.com&utmcs=UTF-8&utmul=en-us&utmdt=PAGE_VIEW_TITLE&utmhid=6413225635&utmp=4.html&utmac=UA-123465-6&utmcc=__utma%3D1.197975304100145214523.2102153242.1405604565.1405604565.15%3B%2B__utmz%3D1.1405604565.1.1.utmcsr%3D(direct)%7Cutmccn%3D(direct)%7Cutmcmd%3D(none)%3B&utmr=&utmip=
我该怎么做才能跟踪其他域名？
