Response (Transport Control)

The following schema describes the transport control data for the HTTP transport.  The HTTP element is the child element of the TransportCtrl element. 

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <xsd:element name="HTTP" type="HTTP"/>
   <xsd:complexType name="HTTP">

        <xsd:element name="Headers" type="Headers" minOccurs="0"/>

   </xsd:complexType>
   <xsd:complexType name="Headers">

   </xsd:complexType>
   <xsd:complexType name="Header">
     <xsd:simpleContent>
        <xsd:extension base="xsd:string">

</xsd:schema>

Response Transport Example

The following is an example of a transport control response structure that "asks" the ISAPI listener to send a 501 error (Not Implemented) back to the client.  The default status codes are 200 (OK) for successfully processed requests, and 500 (Internal Server Error) for failed requests (body contains a <Fault> element). 

<TransportCtrl>
  <HTTP statusCode="501" statusText="Not Implemented"/>
</TransportCtrl>

Tip—Header fields specified in the TransportControl structure will have precedence over the default headers generated by the ISAPI listener (such as "Content-Type:text/xml").
