當RemoteServiceServlet.checkPermutationStrongName()
未能在HttpServletRequest
中找到X-GWT-Permutation HTTP標頭時,我的應用程序偶爾會收到由GWT引發的XSRF攻擊錯誤。當錯誤發生時,下面一行出現在日誌文件:GWT:XSRF:零星丟失X-GWT-Permutation標頭
WARNING: doUnexpectedFailure was invoked.
java.lang.SecurityException: Blocked request without GWT permutation header (XSRF attack?)
該問題已經在這兩個託管模式和Web模式已經經歷了在Firefox 3.x和4.0。
我跑過Live Headers,並且HTTP頭確實缺失。
該應用程序是香草GWT RPC。
任何想法?

這是發生在每一個請求,還是隻有一些?它是隨機的,還是有一種模式? – Rich 2011-03-31 05:08:09
