Attributes and Elements

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

Attributes

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

When allowCookies is set to true, contextChannel will use httpCookies as the mode of exchanging context. When this attribute is set to false, context is exchanged as soap headers.

The default value is false.

You can use this property when you interact with ASMX Web services that use cookies. In this way, you can be sure that the cookies returned from the server are automatically copied to all future client requests for that service.
bypassProxyOnLocal A Boolean value that indicates whether to bypass the proxy server for local addresses. The default is false.
closeTimeout A TimeSpan value that specifies the interval of time provided for a close operation to complete. This value should be greater than or equal to Zero. The default is 00:01:00.
contextProtectionLevel A valid ProtectionLevel value that specifies the desired protection level of the SOAP header used to propagate the context information. The default value is Sign.
hostnameComparisonMode Specifies the HTTP hostname comparison mode used to parse 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 An integer that specifies the maximum buffer pool size for this binding. The default is 524,288 bytes (512 * 1024). Many parts of Windows Communication Foundation (WCF) use buffers. Creating and destroying buffers each time they are used is expensive, and garbage collection for buffers is also expensive. With buffer pools, you can take a buffer from the pool, use it, and return it to the pool once you are done. Thus the overhead in creating and destroying buffers is avoided.
maxReceivedMessageSize A positive integer that specifies the maximum message size, in bytes, including headers, that can be received on a channel configured with this binding. The sender of a message exceeding this limit will receive 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 A string that contains the configuration name of the binding. This value should be unique because it is used as an identification for the binding. Starting with .NET Framework 4, bindings and behaviors are not required to have a name. For more information about default configuration and nameless bindings and behaviors, see Simplified Configuration and Simplified Configuration for WCF Services.
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 be used for emitting messages on the binding. Valid values include the following:

- UnicodeFffeTextEncoding: Unicode BigEndian encoding.
- Utf16TextEncoding: 16-bit encoding.
- Utf8TextEncoding: 8-bit encoding.

The default is Utf8TextEncoding.

This attribute is of type Encoding.
transactionFlow A Boolean value that specifies whether the binding supports flowing WS-Transactions. The default is false.
useDefaultWebProxy A Boolean value that specifies whether the system’s auto-configured HTTP proxy is used. The default is true.

Child Elements

Element Description
<security> Defines the security settings for the binding. This element is of type WSHttpSecurityElement.
<readerQuotas> Defines the constraints on the complexity of SOAP messages that can be processed by endpoints configured with this binding. This element is of type XmlDictionaryReaderQuotasElement.
<reliableSession> Specifies if reliable sessions are established between channel endpoints.

Parent Elements

Element Description
<bindings> This element holds a collection of standard and custom bindings.
