[Openstack] stale data returned even when "X-Newest : True" is used

Hello,

I did a test on a SWIFT cluster to verify the use of X-Newest header with GET/HEAD requests.
However, the GET/HEAD requests are still returning an older copy of the object.
This behavior persists even after 5 hours.

The relevant HTTP headers are given below. SWIFT version is 2.0.3.

I am looking for some guidance on how to debug this on the SWIFT side.

This is the information I received from the people that set up this SWIFT cluster:
====

We have One Haproxy loadbalancer , connected to two SWIFT proxies and then they further connect to 3 storage nodes (12 disk of 2000 GB each).
====

Regards,
Pramodh

PUT updates the object from 37014 bytes to 37200 bytes.
