WS-Addressing policy settings
Use this page to define the appropriate WS-Addressing policy assertions for this policy set.
To view this administrative console page, click
, when the policy set includes the WS-Addressing policy type.You can configure the WS-Addressing policy type for both client-side and provider-side policy sets. If you enable WS-Policy, this configuration is communicated between servers and clients that support WS-Policy.
WS-Addressing is mandatory
Specifies whether a WS-Addressing SOAP header is included on messages.

Messaging style
Specifies the messaging style supported by this policy set.
Use the radio buttons to configure the messaging style.
- Select Synchronous and asynchronous to specify that there is no restriction on the targeting of response messages.
- Select Synchronous only to specify that
response messages must be targeted at the WS-Addressing anonymous
URI. You might want to use this messaging style in the following situations:
- The SOAP headers are not signed, and WS-Security is not enabled. Specifying the synchronous message exchange pattern prevents the server sending messages to a third party, thereby preventing the server from potentially taking part in a Denial of Service attack.
- Clients with a NAT device between themselves and the endpoint. In this configuration, non-anonymous URIs cannot be routed. Use this setting to prevent the client from sending a message containing a ReplyTo endpoint reference with a non-anonymous URI.
- Select Asynchronous only to specify that response messages must not be targeted at the WS-Addressing anonymous URI. This setting does not mean that all non-anonymous URIs are supported, therefore a server can return a fault if it receives a response endpoint reference that it cannot process. You might want to use this messaging style if the endpoint has a very long-running invocation time, and you do not want to hold the connection open while waiting for a response.
The following table shows how the messaging style options correspond
to WS-Policy assertions.
Messaging style | WS-Policy mapping |

Synchronous and asynchronous | wsam:AnonymousResponses or wsam:NonAnonymousResponses |
Synchronous only | wsam:AnonymousResponses |
Asynchronous only | wsam:NonAnonymousResponses |
