因为服务器目前只需要支持php，那么就可以把asp,asp.net都删除了。iis7.5比较好的一点就是全部通过根目录的web.config控制，下面提供这个文件，大家就可以参考一下了
其实就是通过在web.config中添加 <remove name="" />进行删除的，如果想恢复指定的某个映射，可以删除对应的名称即可。

例如这样设置后：

<?xml version="1.0" encoding="UTF-8"?>

<configuration>

 <system.webServer>

  <handlers>

   <remove name="TRACEVerbHandler" />

   <remove name="OPTIONSVerbHandler" />

   <remove name="WebServiceHandlerFactory-ISAPI-2.0-64" />

   <remove name="WebServiceHandlerFactory-ISAPI-2.0" />

   <remove name="WebServiceHandlerFactory-Integrated" />

   <remove name="WebAdminHandler-Integrated" />

   <remove name="TraceHandler-Integrated" />

   <remove name="SSINC-stm" />

   <remove name="SSINC-shtml" />

   <remove name="SSINC-shtm" />

   <remove name="SimpleHandlerFactory-ISAPI-2.0-64" />

   <remove name="SimpleHandlerFactory-ISAPI-2.0" />

   <remove name="SimpleHandlerFactory-Integrated" />

   <remove name="SecurityCertificate" />

   <remove name="PageHandlerFactory-ISAPI-2.0" />

   <remove name="PageHandlerFactory-Integrated" />

   <remove name="HttpRemotingHandlerFactory-soap-ISAPI-2.0-64" />

   <remove name="HttpRemotingHandlerFactory-soap-ISAPI-2.0" />

   <remove name="HttpRemotingHandlerFactory-soap-Integrated" />

   <remove name="HttpRemotingHandlerFactory-rem-ISAPI-2.0-64" />

   <remove name="HttpRemotingHandlerFactory-rem-ISAPI-2.0" />

   <remove name="AXD-ISAPI-2.0-64" />

   <remove name="HttpRemotingHandlerFactory-rem-Integrated" />

   <remove name="AXD-ISAPI-2.0" />

   <remove name="AssemblyResourceLoader-Integrated" />

   <remove name="PageHandlerFactory-ISAPI-2.0-64" />

   <remove name="ASPClassic" />

  </handlers>

 </system.webServer>

</configuration>

在IIS中查看后发现就只有这个了
