Amila Chinthaka Suriarachchi commented on SYNAPSE-913:
------------------------------------------------------
Seems like a problem with the pass through transport. I put some console logs
and check the behaviour of the
org.apache.synapse.transport.passthru.TargetHandler. Although there are two
connections being created only one connection is called with requestReady
method. I am not sure why one is called an other is not called.
In General, for NHttp connections we need to call the submit request method at
the connected method. If we look at the existing nhttp code[1] this has done in
that way. However in the new pass through transport[2] it is called at the
requestReady method (within the request.start(conn)) . Does any one have an
idea about this change?
Then I modify the new pass through to call submit request at the connect
method. After this change all connections established correctly. But second and
third connections did not send a body. This may not be a problem with cloning.
thanks,
Amila.

> Pass Through HTTP Transport for Synapse and Using the Pass Through Transport

> Key: SYNAPSE-913
> URL: https://issues.apache.org/jira/browse/SYNAPSE-913
> Project: Synapse
> Issue Type: Improvement
> Components: Core, Transports
> Environment: Any
> Reporter: Hiranya Jayathilaka
> Fix For: FUTURE
>
> Attachments: patch_with_some_fixes.txt, SYNAPSE_PASS_THRU_8.patch
>
>
> This improvement has 2 main aspects:
> 1. Contributing the pass through HTTP transport developed at WSO2 to Synapse
> 2. Modifying Synapse to use the pass through HTTP transport as the default
> (this requires some minor changes to the transport too)
> The pass through transport, as it stands now, can only be used for simple
> pass through, static routing and header based routing scenarios. It cannot be
> used for any scenario where content lookup or manipulation is required. This
> effort makes the pass through transport one of the core transports of
> Synapse, and modifies Synapse and the transport in a way so that the
> transport can be used in any scenario without restrictions.
