Hi all, I may be wrong, but I don't think this would be a viable and useful option. To my knowledge any http 1.l compliant client MUST be able to receive chunked messages from the server side.
So I think if you need to force the usage of conent length you have to use HTTP 1.0. You still should have the choice to use connection close (normally the default for HTTP 1.0) or keep alive (normally default for HTTP 1.1). Please note, that WSO2 ESB currently always uses keep alive, also using FORCE_HTTP_1.0, but I'm pretty sure the next release will offer support to also use connection close on demand. ;-) Generally you should prefer keep alive due to performance reasons, but there are some older app servers out, which do have there problems with keep alive.
