url请求get方式字符过长

解决方式在<system.webServer>节点下设置maxQueryString值：

<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<modules runAllManagedModulesForAllRequests="true"/>
<security>
<requestFiltering>
<requestLimits maxQueryString="2097151" />
</requestFiltering>
</security>
</system.webServer>
