transport

The transport receives messages from clients and invokes interceptors in the request and response flow. The interceptors that are engaged with the transport are global and are invoked for each message flowing through the router.

Can be used in

beans

Syntax

				<transport coreThreadPoolSize="integer"
							  socketTimeout="integer"
							  tcpNoDelay="[true,false]"
							  httpClientRetries="integer"
							  autoContinue100Expected="[true,false]"
							  printStackTrace="[true,false]">
					<interceptors>
						[interceptors]*
					</interceptors>
				</transport>

Sample

				<beans>
					<transport coreThreadPoolSize="20">
						<ruleMatching />
						<dispatching />
						<userFeature />
						
						<transform xslt="strip.xslt" />
						<wsdlRewriter />
						
						<httpClient />
					</transport>
				</beans>

Attributes

Name	Mandatory	Default	Description	Example
coreThreadPoolSize	no	20	Membrane uses a thread pool to allocate threads to incomming clients connections. The core thread pool size is the minimum number of threads that are created in advance to serve client requests.	5
socketTimeout	no	30000	Socket timout in ms.	60000
tcpNoDelay	no	true		true
httpClientRetries	no	5	Determines how often Membrane tries to send a message to a target before it gives up and returns an error message to the client.	10
autoContinue100Expected	no	true	Whether the HTTP request body should always immediately be requested from the client, if the client sent "Expect: 100-continue" and held back sending the body. As some interceptors need to examine the request body, the recommended value is "true".	true
printStackTrace	no	false	Whether the stack traces of exceptions thrown by interceptors should be returned in the HTTP response.	true
