How to Configure an HTTP Receive Location

You can set HTTP receive location adapter variables either programmatically or by using the BizTalk Server Administration console. If properties are not set in the receive location, the default receive handler values set in the BizTalk Server Administration console are used.

How to Configure an HTTP Receive Location Programmatically

The HTTP adapter stores its configuration information in the BizTalk Management database (also known as the Configuration database). The configuration is stored in a custom XML property bag.

The BizTalk Explorer object model exposes the IReceiveLocation configuration interface, which has a TransportTypeData read/write property. This property accepts the HTTP receive location configuration property bag in a name-value pair XML string.

Setting the TransportTypeData property of the IReceiveLocation is not required. If it is not set, the default values for the HTTP receive location configuration are used. The following table lists the default values, and also lists the configuration properties that you can set in the BizTalk Explorer object model for the HTTP receive location.

The format of the XML string to set these properties is as follows:

<CustomProps>  
   <UseSSO vt="11">-1</UseSSO>  
   <SuspendFailedRequests vt="11">-1</SuspendFailedRequests>  
   <ReturnCorrelationHandle vt="11">-1</ReturnCorrelationHandle>  
   <ResponseContentType vt="8">text/xml</ResponseContentType>  
   <LoopBack vt="11">-1</LoopBack>  
</CustomProps>  

How to Configure an HTTP Receive Location with the BizTalk Server Administration Console

To configure the receive location by using the BizTalk Server Administration console, use the following procedure.

To configure variables for an HTTP receive location

1. Configure Internet Information Services (IIS) to work with HTTP receive locations. For instructions about configuring IIS, see How to Configure IIS for an HTTP Receive Location.

2. In the BizTalk Server Administration console, expand BizTalk Server Administration, expand BizTalk Group, expand Applications, and then expand the application in which you want to create a receive location.

3. In the left pane, click the Receive Ports node. Then in the right pane, right-click the receive port that is associated with an existing receive location or that you want to associate with a new receive location, and then click Properties.

4. In the Receive Port Properties dialog box, in the left pane, select Receive Locations, and in the right pane, double-click an existing receive location or click New to create a new receive location.

5. In the Receive Location Properties dialog box, in the Transport section next to Type, select HTTP from the drop-down list and then click Configure.

6. In the HTTP Transport Properties dialog box, do the following:

   Use this	To do this
   Virtual directory plus ISAPI extension	Specify the name of the virtual directory where you post the messages received by the HTTP/HTTPS receive location. The virtual directory includes the name of the receive location DLL and an optional query string. Examples of virtual directory names are: /<virtual directory>/BTSHTTPReceive.dll /<virtual directory>/BTSHTTPReceive.dll?Purchase%20Order This location must not contain more than one BTSHTTPReceive.dll ISAPI extension, including all subfolders. Type: String Maximum length: 256 Note: The URI for a send port or receive location cannot exceed 256 characters.
   Public Address	Specify the fully qualified URI for this receive location. The value for this property is a combination of the server name and the virtual directory. The BizTalk Messaging Engine exposes this address to external partners. The specified URI should designate the public Web site URL for trading partners to connect to when sending messages to BizTalk Server. This information is optional and is not used by BizTalk Server. This parameter is available to allow administrators to document the public URL that the receive location is tied to. Type: String Minimum length: 0 Maximum length: 256
   Return Content type	Specify the content type of HTTP response messages that the receive location sends back to clients. This property is valid only for request-response receive locations. Default value: text/xml Type: String Minimum length: 0 Maximum length: 256
   Loopback	Define that the request message received on this location is routed either to a send port or back to this receive location to be sent as a response. This property is valid only for request-response receive locations. Default value: False Type: Boolean
   Return correlation handle on success (One way port only)	Define that if successful, the receive location sends the correlation token of the submitted message on the HTTP response to the client. This property is valid only for one-way receive locations. Default value: True Type: Boolean
   Use Single Sign On	Indicate that Enterprise Single Sign-On is used. Default value: False Type: Boolean Note: If this option is enabled then you must also enable the option to Allow Tickets at the SSO System level. The Allow Tickets option is configurable on the Options tab of the SSO System Properties dialog box available in the SSO Administration MMC interface. If this option is enabled and the Allow Tickets option at the SSO System level is not enabled then any messages received by this receive location will be suspended.
   Suspend Failed Requests	Indicate whether or not to suspend HTTP requests that fail inbound processing. A value of False indicates to discard the failed request and send an error status code (401 or 500) to the client. A value of True indicates to suspend the failed request and send an "Accepted" status code (200) to the client for one-way receive ports or an "Error" status code (500) to the client for two-way receive ports. Default value: False Type: Boolean

7. Click OK to save settings.

8. Enter the appropriate values in the Receive Location Properties dialog box to complete the configuration of the receive location and click OK to save settings. For information about the Receive Locations Properties dialog box, see How to Create a Receive Location.

   While the HTTP client calls the HTTP Location, the HTTP adapter authenticates the HTTP client by using either Anonymous, Basic, Digest, or Windows Integrated authentication. If the user is verified, the user context is passed to the receive handler.
