 -   **Multiple Transports and Encodings**  
 
-     Messages can be sent on any of several built-in transport protocols and encodings. The most common protocol and encoding is to send text encoded SOAP messages using is the HyperText Transfer Protocol (HTTP) for use on the World Wide Web. Alternatively, [!INCLUDE[indigo2](../../../includes/indigo2-md.md)] allows you to send messages over TCP, named pipes, or MSMQ. These messages can be encoded as text or using an optimized binary format.  Binary data can be sent efficiently using the MTOM standard. If none of the provided transports or encodings suit your needs you can create your own custom transport or encoding. [!INCLUDE[crabout](../../../includes/crabout-md.md)] transports and encodings supported by [!INCLUDE[indigo2](../../../includes/indigo2-md.md)] see [Transports](../../../docs/framework/wcf/feature-details/transports.md).
