作爲認證用戶，如果我通過外部文本編輯器訪問我的應用程序的網址，mimetype在控制檯顯示爲「*/*」，並且設計好像多次重定向到「/ sign_in」。這是一個問題，因爲如果我轉到「/ foo」，它最初會存儲在會話中作爲身份驗證後返回的路徑。由於重定向的次數，這個值在會話中被吹走了，在設計終於意識到用戶已經登錄後，它最終重定向到「/」。設計變得瘋狂與接受標題的「*/*」
爲了測試，我加入到我的應用程序控制器：
def authenticate_user!
puts "***** AUTHENTICATE USER CALLED!!!"
super
end
所以，如果我直接在瀏覽器中輸入網址，將MIME類型顯示爲HTML，它看到我馬上驗證，一切都呈現爲預期：
Started GET "/products/171" for 127.0.0.1 at 2015-02-11 17:04:53 -0800

Completed 200 OK in 1165ms (Views: 1127.7ms | ActiveRecord: 3.0ms)
然而，當我點擊外部文本編輯器的鏈接，我得到這個瘋狂的行爲：

請注意「重定向到http://localhost:3000/」而不是http://localhost:3000/products/171，這是應該發生的事情。
*/*爲什麼導致這種行爲，我該如何解決這個問題？
UPDATE
顯然的問題是，我得到直接從Chrome的地址欄訪問之間的完全不同的會話，並從單擊外部文本編輯器（鏈接即使文本編輯器簡單地打開Chrome新標籤與URL）：
從鉻單擊外部文本編輯器鏈接後：從把URL直接在Chrome
request.cookies => {"_my_app_session"=>"f32dc5c239fadfc494a775990112f2b5"}
：
request.cookies => {"_my_app_session"=>"91ac136666b78499ea6e071f89cec7ee"}
這是怎麼可能的呢？這是相同的瀏覽器..我認爲瀏覽器中的所有標籤都具有相同的會話，並且您無法更改該標籤？
