僅在首次訪問時出現 http 500 錯誤

第一次訪問網站時，我得到一個500 - Internal server error. 當我點擊重新載入時，該網站工作得很好，並將繼續工作。如果我打開其他瀏覽器或關閉並重新打開目前瀏覽器，則重複該過程。

http://motherscarehawaii.teamvision.biz/

伺服器在 windows server 2008 R2 + sp1 上執行 IIS7.5，這是伺服器上的許多虛擬主機之一，所有其他主機都執行良好。

我看到HTTP/1.1 GET / 503 32 Disabled motherscarehawaii.teamvision.biz列出C:\Windows\System32\LogFiles\HTTPERR\httperr1.log但不確定禁用了什麼。應用程序池設置為在經典模式下與 .Net Framework v2.0.50727 一起執行。

任何想法是導致錯誤的原因以及如何解決它？

這與會話 cookie 以及站點如何處理它們有關。

第一次通過，我最後沒有會話cookie，

$ wget --load-cookies cookies --save-cookies cookies --keep-session-cookies -S http://motherscarehawaii.teamvision.biz/

第二遍，現在從文件中載入cookie，

我希望這可以幫助您進一步追踪它。
