Same work for following proxy definition for the curl request, curl -X GET
http://localhost:8283/services/StockQuoteProxy/mobile/bbb
<proxy name="StockQuoteProxy">
<target>
<endpoint>
<address uri="
http://localhost:9768/services/MobileDirectoryService"; format="rest"/>
</endpoint>
<outSequence>
<send/>
</outSequence>
</target>
</proxy>
The trace is now,
client to ESB:
GET /services/StockQuoteProxy/mobile/bbb HTTP/1.1
User-Agent: curl/7.21.7 (x86_64-redhat-linux-gnu) libcurl/7.21.7 NSS/

Host: 127.0.0.1:8283
Accept: */*
ESB to service:
GET /services/MobileDirectoryService/mobile/bbb HTTP/1.1
