it to object server so that it can determine which version is a better choice based on system metadata. If current version is not good choice, reply a redirect response to tell proxy server the right one. Another solution can be based on object versioning

<tt><font face="Courier New">Wrt your second question, there are copies of the rings on object servers as well and they are used for lookup in various scenarios, replication for one. As an example take a small 6 node cluster where all servers are running all
services, if an admin adds/deletes a device from the ring they do so on one of the nodes and then copes the .gz file to all the others. During the window when the first node detects the new ring file and .gz files are copied to all the other nodes and detected/brought
into memory, any responses fielded by the proxy service on the other nodes will have older ring info than the first node updated. Another case could be a larger cluster where there's a proxy tier and a capacity tier (not all services running everywhere).
The admin could update the ring on any node and copy the ring files on the nodes in any order - if any capacity node gets an update before any proxy node you can run into the same scenario. The ring versions blueprint was John's s!</font></tt><br>

<br>
<tt><font face="Courier New">Hi Paul,</font></tt><br>
<br>
<tt><font face="Courier New">Can you explain more about the two use cases referenced?</font></tt><br>
<br>
<tt><font face="Courier New">Object Variation seems like a nice idea, but can you clarify how the mechanism would work to get at the variations? Any examples? From the current descriptions, it seems like the LFS Patch could help here without adding anything
to the object server.</font></tt><br>
<br>
<tt><font face="Courier New">Regarding the ring updates, given that rings are used by the proxy servers, and as far as I can tell, the object servers don't know about the rings, how would object servers have more up-to-date knowledge to perform the redirect?</font></tt><br>
<br>
<tt><font face="Courier New">Thanks,</font></tt><br>

<tt><font face="Courier New">> 1) This is a capability that would be checked in independent of other

</font></tt><br>

<tt><font face="Courier New">> this makes more sense as a 5xx response with additional information
