Asp.net查询请求QueryString过长问题

Web.confg配置调整如下：

<configuration>
  <system.web>
    <httpRuntime targetFramework="4.5" maxQueryStringLength="2097151"/>
  </system.web>
  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxQueryString="2097151" />
      </requestFiltering>
    </security>
  </system.webServer>
</configuration>
