How to Configure an HTTP Send Port

  • Artikkel

You can configure an HTTP send port either programmatically or by using the BizTalk Server Administration console.

Configure an HTTP send port programmatically

The HTTP adapter stores its configuration information in the BizTalk Management database (also known as the Configuration database). You store configuration information in a custom XML property bag. During initialization of the HTTP adapter and during its run time, the server passes the configuration to the adapter as follows:

  • For the HTTP send handler, configuration information passes to the adapter by calling the Load method of the IPersistPropertyBag interface.

  • For the HTTP send ports, configuration information passes to the adapter as a set of properties on a message context. The HTTP namespace groups these properties together.

    The BizTalk Explorer object model exposes the ItransportInfo adapter configuration interface for send ports, which contains the TransportTypeData read/write property. This property accepts the HTTP send port configuration property bag as a name/value pair XML string. Note that to set this property in the BizTalk Explorer object model, it must first be set on the Address property of the ITransportInfo interface.

    Setting the TransportTypeData property of the ITransportInfo interface is not required. If it is not set, the HTTP adapter will use the default values for the HTTP send handler.

    If send port configuration properties that duplicate the configuration for the handler are not defined, configuration properties for the handler are used. If the HTTP send handler does not have configuration values, the HTTP send adapter logs an error in the event log and moves the message to the backup adapter.

    You can set configuration properties programmatically on a message context. You can set these properties in a BizTalk Server orchestration schedule or in custom pipeline components. The following rules apply when using these properties:

  • If the configuration property is set on an orchestration or in a custom pipeline component in a receive pipeline, then:

    • If a message is sent to a static send port, the property value will be overwritten with the value configured for that send port.

    • If a message is sent to a dynamic send port, the property value will not be overwritten.

  • If the configuration property is set in a custom pipeline component in a send pipeline, then:

    • The value will not be overwritten regardless of whether the message is sent to a static or dynamic send port.

    The following table lists the configuration properties that you can set in the BizTalk Explorer object model for the HTTP send location.

Configure an HTTP send port with the BizTalk Server Administration console

You can set HTTP send port adapter variables in the BizTalk Server Administration console. If properties are not set for the send port, the default send handler values set in the BizTalk Server Administration console are used.

Note

The configuration properties described in this topic are common for both one-way and request-response HTTP send ports.

  1. In the BizTalk Server Administration console, create a new send port or double-click an existing send port to modify it. See How to Create a Send Port for more information. Configure all of the send port options and specify HTTP for the Type option in the Transport section on the General tab.

  2. On the General tab, in the Transport section, click the Configure button next to Type.

  3. In the HTTP Transport Properties dialog box, on the General tab, do the following:

    Use this To do this
    Destination URL Required. Specify the address to send HTTP requests. Include query strings appended to the base URL.

    Type: String

    Maximum length: 256

    For more information, see Restrictions on the Destination URL Property. Note: The URI for a send port or receive location cannot exceed 256 characters.
    Enable chunked encoding Specify to use chunked encoding. If this option is enabled, the HTTP adapter will use HTTP chunked encoding with maximum chunk size of 8 KB. Chunked encoding is implicitly disabled if the HTTP send handler is configured to Use proxy.

    Type: Boolean

    Default Value: True
    Request timeout (sec) Specify the time-out in seconds for the HTTP/HTTPS transmission. If the HTTP adapter does not receive the response within this time, the service logs the error and resubmits the message based on the retry infrastructure.

    If set to zero (0), the BizTalk Messaging Engine calculates the time-out based on the request message size. If you do not provide a value, the value for the handler is used.

    Type: Long

    Minimum value: 0

    Maximum value: MAX_LONG
    Maximum redirects Specify the maximum redirects allowed for the message being sent.

    Default value: 5

    Type: Int

    Minimum value: 0

    Maximum value: 10
    Content type Specify the content type of the request messages.

    If this value is not set, the value for the handler is used.

    Type: String

    Minimum length: 0

    Maximum length: 256

  4. In the HTTP Transport Properties dialog box, on the Proxy (Handler override) tab, do the following:

    Use this To do this
