Settings for the HTTP Outbound Adapter
The outbound HTTP adapter has the following settings:
|Basic Settings||HTTP Server, HTTP Port, URL, Credentials|
|Connection Settings||SSL Configuration, SSL Check Server Identity, Proxy Server, Proxy Port, Proxy HTTPS, Proxy Http Tunnel, Response Timeout, ConnectTimeout, WriteTimeout, LocalInterface|
The remaining settings are common to all business operations. For information, see Settings for All Business Operations.
Specifies the number of seconds to wait for the connection to the server to open. The default value is 5.
If the connection is not opened in this time period, the adapter retries repeatedly, up to the number of times given by Failure Timeout divided by Retry Interval.
ID of the production credentials that can authorize a connection to the given destination URL. For information on creating production credentials, see Configuring Productions.
TCP port on the server to send HTTP requests to (will use 80 by default, or 443 if SSLConfig is specified). Values other than 80 are included in the Host: header of the HTTP request that you are sending. For more information, see Specifying the Destination Server and URL Path.
IP address of the server to send HTTP requests to. This is used in the Host: header of the HTTP request that you are sending. Also see Specifying the Destination Server and URL Path.
Specifies the network interface through which the HTTP connection should go. Select a value from the list or type a value. An empty value means use any interface.
If using a proxy server, indicates whether the proxy server communicates with the target system using HTTPS. If you enable this option and specify a value in the Proxy Server property, then the proxy server issues requests for HTTPS pages rather than HTTP pages. Additionally, enabling this option changes the default HTTP Port to 443, which is the HTTPS port.
If using a proxy server, specifies the port on the proxy server to connect to. The default value is 8080.
If using a proxy server, specifies the proxy server host name. Request are made to the proxy server that you specify on the Proxy Port that you specify. If you do not specify a value, a proxy server is not used.
Proxy HTTP Tunnel
Specifies whether the adapter uses the HTTP CONNECT command to establish a tunnel through the proxy to the target HTTP server. If true, the request uses the HTTP CONNECT command to establish a tunnel. The address of the proxy server is taken from the Proxy Server and Proxy Port properties. If Proxy Https is true, then once the tunnel is established, InterSystems IRIS® negotiates the TLS connection. The default value is false.
Specifies the timeout for getting a response from the server (the timeout for opening the connection to the server is set by ConnectTimeout). The default value is 30.
If no response is received, the adapter retries repeatedly, up to the number of times given by Failure Timeout divided by Retry Interval.
SSL Check Server Identity
Specifies that when making a TLS connection, the adapter should check that the server identity in the certificate matches the name of the system being connecting to. This defaults to specifying that the check should be made. Uncheck this for test and development systems where the name specified in the TLS certificate does not match the DNS name.
The name of an existing TLS configuration to use to authenticate this connection. Choose a client TLS configuration, because the adapter initiates the communication.
To create and manage TLS configurations, use the Management Portal. See InterSystems TLS Guide. The first field on the Edit SSL/TLS Configuration page is Configuration Name. Use this string as the value for the SSL Configuration setting.
The SendSuperSession is a Boolean setting that controls whether the outbound adapter creates a SuperSession header in the HTTP header and assigns an identifier to it. When finding a message, you can use the SuperSession value to match a message in one production with the related message in another production. Within a production, it is easy to track a message as it travels between business services, processes, and operations using the SessionId. But once a message leaves a business operation via an HTTP message and enters a different production, the production receiving the message assigns a new SessionId.
If SendSuperSession is selected, the HTTP outbound adapter does the following:
Check if the message has an empty value in Ens.MessageHeaderBase.SuperSession property. If it does have an empty value, the adapter generates a new value and stores it in the SuperSession property.
Stores the value of the SuperSession property in the private InterSystems.Ensemble.SuperSession HTTP header of the outgoing message.
When an HTTP incoming adapter receives a message, it checks for the SuperSession value in the incoming HTTP message header. If the value is present, it sets the Ens.MessageHeaderBase.SuperSession property. This property is preserved as the message passes from one production component to another.
There are no tools to automate tracking messages between productions using SuperSession.
URL path to request from the server (not including http:// or the server address).
Specifies whether to save cookies received in HTTP responses while this adapter is instantiated, and insert them in each subsequent HTTP request.
Specifies a timeout value for writes to the web server. If this setting is null, there is no timeout.
