Subject [jira] [Commented] (SYNAPSE-992) Adding the default Content-Type when there is no body in the response
Date Fri, 19 Sep 2014 03:34:34 GMT

    [ https://issues.apache.org/jira/browse/SYNAPSE-992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14139926#comment-14139926

Hiranya Jayathilaka commented on SYNAPSE-992:
---------------------------------------------

I'm not entirely confident about this fix. All this content type inference code is guarded
by an if condition right now:

if (expectEntityBody) {
  ...
}

So perhaps a better solution is to set the expectEntityBody to false to cover your scenario
(Content-Length = 0; Content-Type = null;). This is a vert specific case, and we can easily
check for it and set the boolean value to false early in the flow. Can you please look into
that option please? Take a look at the TargetHandler#isResponseHaveBodyExpected() method.

> When there is no content type in the response synapse set the default content type as
"application/octet-stream".
> The HTTP Spec only talks about dealing with Content-Types and assuming "application/ocet-stream"
for messages, containing an entity-body [1]. As we are not providing an entity body, the ESB
should not infer a Content-Type.
> Instead of, the ESB just should pass through the response to the client without adding
a Content-Type.
