The Proxy Server is responsible for connecting to the rest of the OpenStack Object Storage architecture. For each request, it looks up the location of the account, container, or object in the ring and route the request accordingly. The public API is also exposed through the proxy server. When objects are streamed to or from an object server, they are streamed directly through the proxy server to or from the user – the proxy server does not spool them.

The configurable options pertaining to proxy server are stored in /etc/swift/proxy-server.conf. The following is the sample proxy-server.conf file:

[app:proxy-server]
use = egg:swift#proxy
allow_account_management = true
account_autocreate = true

[filter:tempauth]
use = egg:swift#tempauth
user_admin_admin = admin.admin.reseller_admin
user_test_tester = testing .admin
user_test2_tester2 = testing2 .admin
user_test_tester3 = testing3

[filter:healthcheck]
use = egg:swift#healthcheck 

[filter:cache]
use = egg:swift#memcache

By default, Unified File and Object Storage is configured to support HTTP protocol and uses temporary authentication to authenticate the HTTP requests.
