錯誤消息：狀態信息對於此頁無效並可能已損壞（無效的視圖狀態）

Question

我有兩臺服務器IIS6負載均衡由負載平衡硬件完成。當響應提供Server 1和回發由Server 2處理它總是會得到一個錯誤The state information is invalid for this page and might be corrupted和下方Invalid viewstate上幾乎每回發當請求被替代服務器來處理。 如果我關閉其中一臺服務器，那麼它似乎工作正常。

我檢查了decryptionKey和validationKey都是正是同樣在這兩個服務器的部署，也問心無愧enableEventValidation="false"和enableViewStateMac="false"。 Google提供的各種解決方案都沒有運氣：P

請檢查以下堆棧跟蹤，其中exception出現在HiddenFieldPageStatePersister.Load()後面跟着Page.LoadPageStateFromPersistenceMedium()。

注：有沒有AJAX/JavaScript的相關的事情搞砸了我的申請。

在此先感謝。
