昨天晚上配置myblog的rewrite。发现一个奇怪的问题。由于现在使用的这个pjblog，为了让搜索引擎收录的连接有效。我想把原来的asp连接rewrite到我的新程序上面。所以有这样一条规则。

    <rule>
        <from>^/article.asp\?id=(.*)$</from>
        <to type="redirect">/entry/$1.jhtml</to>
    </rule>

但是我这样的连接总是匹配不到，只要去掉那个？就可以了。这个正则表达式是没有问题的。/article.asp?id=64是可以匹配的到的。
后来看3.0的manual (http://tuckey.org/urlrewrite/manual/3.0/)才发现原来是这个的问题。
