URLRewrite - 添加.do到傳入的請求 - 但過濾器執行引發異常

我剛從http://tuckey.org/安裝了URL重寫過濾器。URLRewrite - 添加.do到傳入的請求 - 但過濾器執行引發異常

我已經添加了一條規則，以便爲來自特定路徑/beta的請求添加.do。

<rule> 
     <from>(.*)/beta/(.*)\?(.*)</from> 
     <to>$1/beta/$2.do\?$3</to> 
    </rule> 

    <rule> 
     <from>(.*)/beta/(.*)</from> 
     <to>$1/beta/$2.do</to> 
    </rule>

規則配置進入狀態OK，因此它已成功加載。

不幸的是，現在我在日誌中看到一個超過5000留置長的異常堆棧跟蹤，似乎陷入循環。

看來你的規則遞歸循環，因爲目標URL匹配<from>子句中的正則表達式。嘗試重寫正則表達式只匹配from表達式，而不是to生成的url。即

<rule> 
    <from>(.*)/beta/(.*)</from> 
    <to>$1/beta2/$2.do</to> 
</rule>
