This is a security feature. Do not change this feature unless the scope of the change is fully understood. You can configure the IIS server to reject requests whose query string is greater than a specified value. If the request's query string is greater than the configured value, this error is returned. If the allowed length of the query string needs to be increased, modify the configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString setting.

This is a security feature. Do not change this feature unless the scope of the change is fully understood. You can configure the IIS server to reject requests whose query string is greater than a specified value. If the request's query string is greater than the configured value, this error is returned. If the allowed length of the query string needs to be increased, modify the configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString setting.
