今天，测试发现在
https://mlogin.vip.com/user-login.html?back_act=http%3A%2F%2Fm.vip.com%2Fuser.html
下上报监控数据
http://mstats.vip.com/v1/timing/m?_t=1420647129290&p2=240&p4=377&t0=0&t1=63&t2=474&t3=642&t4=1&t6=411&t7=919&t8=3&t9=1059
老是报412：
GET http://mstats.vip.com/v1/timing/m?_t=1420647129290&p2=240&p4=377&t0=0&t1=63&t2=474&t3=642&t4=1&t6=411&t7=919&t8=3&t9=1059 412 (Precondition Failed)
看了监控平台的代码，返回状态码412是因为监控平台需要通过Referer头部来判断平台，但是该次请求却无Referer头部：
GET /v1/timing/m?_t=1420647129290&p2=240&p4=377&t0=0&t1=63&t2=474&t3=642&t4=1&t6=411&t7=919&t8=3&t9=1059 HTTP/1.1

确实请求头没有Referer头部，原来是因为HTTP协议规定：
Clients SHOULD NOT include a Referer header field in a (non-secure) HTTP request if the referring page was transferred with a secure protocol.
