遇到的问题就是rewriter不起效果冲IIS6迁移过来的。最后发现是Framework 4.0的原因！记录处理方式为：
一、
<configSections>
<section name="rewriter" requirePermission="false" type="Intelligencia.UrlRewriter.Configuration.RewriterConfigurationSectionHandler, Intelligencia.UrlRewriter" />
</configSections>
二、
<httpModules>
<add type="Intelligencia.UrlRewriter.RewriterHttpModule,Intelligencia.UrlRewriter" name="UrlRewriter" />
</httpModules>
三、
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<handlers>
<add name="all" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv4.0,bitness32" />
<add name="htmls" path="*.html" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Script" preCondition="classicMode,runtimeVersionv2.0,bitness32" />
</handlers>
</system.webServer>
最重要是第三步 4.0 必须要。ok了！
