Affan Dar commented on PROTON-136:
Here is a scenario that might not work if the notion of ssl context is not
exposed in the messenger API:
+ Client attempts to send a message to endpoint ep1 and as a result the SSL
negotiation happens but at the end the server redirects it to endpoing ep2
+ Client now needs to resend the same message to ep2 but wants to reuse the
session id from above since
If the session cache in the messenger api is keyed off of the endpoint name
then this won't work. Also the knowledge that the session for ep1 should be
reused for ep2 is very app specific.
This is very handy in cases when i) the session cache is shared between a
server farm OR ii) the server is redirecting to itself (e.g. to bypass a load
> Add support for SSL session resumption
> Key: PROTON-136
> URL: https://issues.apache.org/jira/browse/PROTON-136
> Project: Qpid Proton
> Issue Type: New Feature
> Components: proton-c
> Affects Versions: 0.3
> Reporter: Affan Dar
> Assignee: Ken Giusti
> Labels: ssl, sslContext, sslresume
> Open SSL supports resumption of SSL sessions which by-pass the heavy SSL
> handshake process. This is critical for scenarios involving low powered
> devices especially on cellular data networks where bandwidth is precious.
> It would be great if Proton exposes this ssl resume feature to users. .
