我有一个嵌入在 iframe 中的网站。
有时我会看到为每个 get 或 post 生成一个幻像 get 请求。
nginx 日志显示了这种情况，请注意在发布后立即发送了一个 get 请求：
XX.XXX.XXX.XX - - [06/Oct/2012:20:55:47 +0000] "POST /website_widget/users HTTP/1.1" 200 1996 "http://subdomain.mysite.com/website_wi
dget/users/sign_up" "Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/20100101 Firefox/15.0.1"
XX.XXX.XXX.XX - - [06/Oct/2012:20:55:47 +0000] "GET /website_widget/users HTTP/1.1" 404 781 "http://subdomain.mysite.com/website_widg
et/users" "Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/20100101 Firefox/15.0.1"
XX.XXX.XXX.XX - - [06/Oct/2012:20:55:53 +0000] "POST /website_widget/users HTTP/1.1" 200 1993 "http://subdomain.mysite.com/website_wi
dget/users" "Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/20100101 Firefox/15.0.1"
XX.XXX.XXX.XX - - [06/Oct/2012:20:55:53 +0000] "GET /website_widget/users HTTP/1.1" 404 781 "http://subdomain.mysite.com/website_widg
et/users" "Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/20100101 Firefox/15.0.1"
这也发生在标准的 get 请求中。从我的 Rails 日志中，我可以看到：
Started GET "/website_widget/users/sign_in" for XX.XX.XXX.XX at 2012-10-06 20:45:35 +0000
[b7e895726057452d0af6a2ac5cd1668d] Processing by WebsiteWidget::MyController#new as HTML
Started GET "/website_widget/users/sign_in" for XX.XX.XXX.XX at 2012-10-06 20:45:37 +0000
[b20e57fcc205ee6cf958589ab1660c9f] Processing by WebsiteWidget::MyController#new as */*
请注意*/*第二个日志条目，这表明 mime 类型未设置为 html 或根本未设置。
以前有人遇到过这种事情吗？或者知道如何进一步调试它。我证明很难重新创建。
