</configuration>-----------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------网上找的配置文件：
<?xml version="1.0" encoding="utf-8"?>
<configuration>  <configSections>
    <section name="rewriter" requirePermission="false" type="Intelligencia.UrlRewriter.Configuration.RewriterConfigurationSectionHandler, Intelligencia.UrlRewriter"/>

    <httpModules>
      <add type="Intelligencia.UrlRewriter.RewriterHttpModule,Intelligencia.UrlRewriter" name="UrlRewriter"/>
    </httpModules>
  </system.web></configuration>这样是没问题的，不知道什么原因？

Answer 2

没有找到Intelligencia.UrlRewriter.RewriterHttpModule这个文件。确认这个dll部署过去了。

Answer 3

这么逗？
配置中不添加UrlRewriter就能正常运行，那说明你的代码没用到这个模块，那就不要添加啊，反正你又不用。

Answer 4

暂时解决了，在web.config中增加了如下：
<system.webServer>
    　<modules runAllManagedModulesForAllRequests="true">
      　<add name="UrlRewriter" type="Intelligencia.UrlRewriter.RewriterHttpModule"/>
      　</modules>
      　<validation validateIntegratedModeConfiguration="false"/>
  </system.webServer>
