Tomcat 使用UrlRewriteFilter显示此网页具有重定向循环

我正在使用

UrlRewriteFilter

将

example.com

转换为

www.example.com

<urlrewrite>
    <rule>
      <name>Canonical Hostnames</name>
      <condition name="host" operator="notequal">^example.com</condition>
      <condition name="host" operator="notequal">^$</condition>
      <from>^/(.*)</from>
      <to type="redirect" last="true">http://www.example.com/$1</to>
    </rule>
</urlrewrite>

规范主机名
^example.com
^$
^/(.*)
http://www.example.com/$1

当我浏览

example.com

时，浏览器显示

此网页有一个重定向循环

^example.com

<urlrewrite>
    <rule>
      <name>Canonical Hostnames</name>
      <condition name="host" operator="notequal">^example.com</condition>
      <condition name="host" operator="notequal">^$</condition>
      <from>^/(.*)</from>
      <to type="redirect" last="true">http://www.example.com/$1</to>
    </rule>
</urlrewrite>

将上述内容替换为以下内容之一

^example\.com

<urlrewrite>
    <rule>
      <name>Canonical Hostnames</name>
      <condition name="host" operator="notequal">^example.com</condition>
      <condition name="host" operator="notequal">^$</condition>
      <from>^/(.*)</from>
      <to type="redirect" last="true">http://www.example.com/$1</to>
    </rule>
</urlrewrite>

---

^www.example\.com

但问题是

http://example.com/resetpassword/?user=2560256&token=1233

被重定向到

http://example.com/resetpassword

<urlrewrite>
    <rule>
      <name>Canonical Hostnames</name>
      <condition name="host" operator="notequal">^example.com</condition>
      <condition name="host" operator="notequal">^$</condition>
      <from>^/(.*)</from>
      <to type="redirect" last="true">http://www.example.com/$1</to>
    </rule>
</urlrewrite>
