Description RHOS Integration 2013-12-12 16:50:29 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/swift/+spec/swift-account-head-caching.

Description:

John was pointing on IRC that the headers on a account HEAD are not served from the cache while we can do some clever things there.

Although stored in the cache :

http://git.io/cakjlg

we are not using it.

The conditions are :

As long it is a simple HEAD without a query string and there's info about it in the memcache just return that.

If it has a X-Newest headers it has to go to the storage nodes and not served by the cache (i.e: see code from here http://git.io/a98tuQ)
