URL Rewrite Filter不使用包含特殊字符的查询参数

Question

I'm using URL Rewrite Filter to forward some ugly URLs to pretty Urls. Referring to Conditions Based On URL Parameters , I've done something using UrlRewriteFilter which is actually required to make my site Google crawl-able. Here's how it goes.

<rule enabled="true">
        <note>
            The rule means that requests to /test/status/ will be redirected to /rewrite-status
            the url will be rewritten.
        </note>
        <condition type="parameter" name="_escaped_fragment_" operator="equal">(apple|kiwi|orange)</condition>
            <from>^/mysite/(.+)/(.*)$</from>
            <to type="redirect">/mysite/%{parameter:_escaped_fragment_}</to>
    </rule>

It fails throwing java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern – %%7. As my variable contains underscores (_escaped_fragment_), where in it works fine with a parameter variable called 'friuit'. Please help me get out of it.

Answer 1

<rule>
<condition name="_escaped_fragment_" type="parameter" operator="equal">(apple|kiwi|orange)</condition>
<to type="redirect">/mysite/%1</to>
</rule>

Using the value of a query parameter with %{parameter:_escaped_fragment_} would work only with words containing no special characters. where in %1 (that is % followed by query parameter index) will work for any, which solved my problem.
