Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute Description

allowCookies

A value that indicates whether the client accepts cookies and propagates them on future requests. The default is false.

You can use this property when you interact with ASP.NET Web services (ASMX) that use cookies. This ensures that cookies that the server returns are automatically copied to all future client requests for that service.

bypassProxyOnLocal

A value that indicates whether to bypass the proxy server for local addresses. The default is false.

closeTimeout

A TimeSpan value that specifies the time interval for a close operation to complete. This value should be greater than or equal to Zero. The default is 00:01:00.

hostnameComparisonMode

Specifies the HTTP hostname comparison mode used to parse Uniform Resource Identifiers (URIs). This attribute is of type HostnameComparisonMode, which indicates whether the hostname is used to reach the service when matching on the URI. The default value is StrongWildcard, which ignores the hostname in the match.

maxBufferPoolSize

The maximum buffer pool size for this binding. The default is 524,288 bytes (512 × 1,024). Many parts of Windows Communication Foundation (WCF) use buffers. Creating and destroying buffers each time they are used is expensive, as is garbage collection for buffers. With buffer pools, you can take a buffer from the pool, use it, and return it to the pool when you are done. This avoids the overhead in creating and destroying buffers.

maxReceivedMessageSize

The maximum message size, in bytes, including headers, which a channel configured with this binding, can receive. The sender of a message exceeding this limit receives a SOAP fault. The receiver drops the message and creates an entry of the event in the trace log. The default is 65536.

messageEncoding

Defines the encoder used to encode the message. Valid values include the following:

  • Text: Use a text message encoder.

  • Mtom: Use a Message Transmission Organization Mechanism 1.0 (MTOM) encoder.

The default is Text.

This attribute is of type WSMessageEncoding.

name

The configuration name of the binding. This value should be unique because it is used as an identification for the binding.

openTimeout

A TimeSpan value that specifies the interval of time provided for an open operation to complete. This value should be greater than or equal to Zero. The default is 00:01:00.

proxyAddress

A URI that specifies the address of the HTTP proxy. If useSystemWebProxy is true, this setting must be null. The default is null.

receiveTimeout

A TimeSpan value that specifies the interval of time provided for a receive operation to complete. This value should be greater than or equal to Zero. The default is 00:01:00.

sendTimeout

A TimeSpan value that specifies the interval of time provided for a send operation to complete. This value should be greater than or equal to Zero. The default is 00:01:00.

textEncoding

Specifies the character set encoding to use for emitting messages on the binding. Valid values include the following:

  • UnicodeFffeTextEncoding: Unicode Big Endian encoding.

  • Utf16TextEncoding: 16-bit encoding.

  • Utf8TextEncoding: 8-bit encoding.

The default is Utf8TextEncoding.

This attribute is of type Encoding.

transactionFlow

A value that specifies whether the binding supports flowing WS-Transactions. The default is false.

useDefaultWebProxy

A value that specifies whether the system’s auto-configured HTTP proxy is used. The default is true.

Child Elements

Element Description

<security> of <wsHttpBinding>

Defines the security settings for the binding. This element is of type WSHttpSecurityElement.

<readerQuotas>

Defines the constraints on the complexity of SOAP messages that endpoints configured with this binding can process. This element is of type XmlDictionaryReaderQuotasElement.

<reliableSession> element

Specifies whether reliable sessions are established between channel endpoints.

Parent Elements

Element Description

<bindings>

This element holds a collection of standard and custom bindings. Each entry is identified by its name. Services use bindings by linking them using the name.

Remarks

The WS2007HttpBinding adds a system-provided binding similar to WSHttpBinding but uses the Organization for the Advancement of Structured Information Standards (OASIS) standard versions of the ReliableSession, Security, and TransactionFlow protocols. No changes to the object model or default settings are required when using this binding.

Example

<configuration>
    <system.ServiceModel>
        <bindings>
            <ws2007HttpBinding>
                <binding name="test"
                    closeTimeout="00:00:10"
                    openTimeout="00:00:20" 
                    receiveTimeout="00:00:30"
                    sendTimeout="00:00:40"
                    bypassProxyOnLocal="false"
                    transactionFlow="false" 
                    hostNameComparisonMode="WeakWildcard"
                    maxReceivedMessageSize="1000"
                    messageEncoding="Mtom" 
                    proxyAddress="http://foo/bar"
                    textEncoding="utf-16"
                    useDefaultWebProxy="false">
                    <reliableSession ordered="false"
                         inactivityTimeout="00:02:00"
                         enabled="true" />
                    <security mode="Transport">
                         <transport clientCredentialType="Digest"
                            proxyCredentialType="None"
                            realm="someRealm" />
                         <message clientCredentialType="Windows"
                            negotiateServiceCredential="false"
                            algorithmSuite="Aes128" 
                            defaultProtectionLevel="None" />
                    </security>
                </binding>
           </ws2007HttpBinding>
        </bindings>
    </system.ServiceModel>
</configuration>
