How to make inSequence without send - esb

Question

I have this WSO2 ESB proxy:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="sid008" transports="http" startOnLoad="true" trace="disable">
<target>
<inSequence>
<switch source="get-property('inquiryId')">
<log level="full"/>
<case regex="">
<send/>
</case>
<default>
</default>
</switch>
</inSequence>
<outSequence>
<....some processing..>
<send/>
</outSequence>
</target>
<publishWSDL key="CommonService.wsdl">
<resource location="request.xsd" key="request.xsd"/>
<resource location="response.xsd" key="response.xsd"/>
<resource location="SMEV.xsd" key="SMEV.xsd"/>
<resource location="statusAndError.xsd" key="statusAndError.xsd"/>
</publishWSDL>
</proxy>
In this proxy in default case doesn't run outSequence without send mediator. How can I do it without send mediator

Answer 1

Try this config for :
<default>
<... some processing ...>
<header action="remove" name="To"/>
<property action="set" name="RESPONSE" scope="default" type="STRING" value="true"/>
<send/>
</default>
With this config, you'll send response to client directly from inSequence part (you won't get into outSequence).

Answer 2

The rational behind In and Out sequence is:
In seq : When a message comes to a proxy service from a client, it always goes to the In sequence.
Out Seq: When a proxy service sends a message out from ESB to a backend service, the response will always come to Out seq (Unless specify the sequence using receiving seq.)
Hope this helps.
