""" """
LastModified is a middleware that add a meta to a container
when that container and/or objects in it are modified. The meta
data will contains the epoch timestamp. This middleware aims
to be used with the synchronizer. It limits the tree parsing
by giving a way to know a container has been modified since the
last container synchronization.
Actions that lead to the container meta modification :
- POST/PUT on container
- POST/PUT/DELETE on object in it
The following shows an example of proxy-server.conf:
[pipeline:main]
pipeline = catch_errors cache tempauth last-modified proxy-server
[filter:last-modified]
use = egg:swift#last_modified
