mule 3.5 follow redirects on outbound endpoint - http

Question

I have the simple flows as following. When we hit one flow, it hits another flow and gets http.status 302 and Location , which means it must redirect to the location in Location header. But it is throwing exception.
<flow name="httpconnectorFlowRedirection">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="9876" path="redirect" connector-ref="NoSessionEncodingConnector" doc:name="HTTP"/>
<http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="9876" method="POST" doc:name="HTTP" path="temp" connector-ref="NoSessionEncodingConnector" contentType="text/plain"
followRedirects="true" />
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
</flow>
<flow name="temp_flow">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="9876" path="temp" connector-ref="NoSessionEncodingConnector" doc:name="HTTP" />
<logger message="in temp flow" level="INFO" doc:name="Logger"/>
<set-property propertyName="http.status" value="307" doc:name="Property" />
<set-property propertyName="Location" value="http://localhost:9876/samplehttp" doc:name="Property" />
</flow>
Error I am getting is as follows
org.mule.exception.DefaultMessagingExceptionStrategy:

I am getting this error only when follow redirects set to true on outbound endpoint
I am using mule 3.5.

Answer 1

I got the answer. I need to use GET reqeust for successful redirection.
But if I use http listeners(since mule 3.6), I am able to redirect even for POST requests. Consider the following example.
<http:listener-config name="GlobalHTTPConnector" host="localhost" port="9876" doc:name="HTTP Listener Configuration" basePath="mulelearning"/>
<flow name="redirection-flow">
<http:listener config-ref="GlobalHTTPConnector" path="/requestredir" doc:name="HTTP"/>
<!--
When followRedirects is set to true, when http.status from called service is redirection(eg:301), it redirects to new location.
In this case /redFlow1 sends a redirection code 301 and location header. Hence it redirects to /redFlow2 (see the flows below) and gives us the response 'payload from red-flow2'
-->
<http:request config-ref="HTTP_Request_Configuration" path="/redFlow1" method="POST" followRedirects="true" doc:name="HTTP" />
</flow>
<flow name="red-ser1">
<http:listener config-ref="GlobalHTTPConnector" path="/redFlow1" doc:name="HTTP"/>
<logger level="INFO" doc:name="Logger" message="I am in red-flow1"/>
<set-payload value="payload from red-flow1" />
<set-property propertyName="http.status" value="301" doc:name="Property" />
<set-property propertyName="Location" value="http://localhost:9876/mulelearning/redFlow2" doc:name="Property" />
</flow>
<flow name="red-ser2">
<http:listener config-ref="GlobalHTTPConnector" path="/redFlow2" doc:name="HTTP"/>
<set-payload value="payload from red-flow2" />
<logger level="INFO" doc:name="Logger" message="I am in red-flow2"/>
</flow>
