Cloud Files authentication re-use #2876
Description
93e4b56 created the issue
Optimization tip: When the Log Drawer is open, I can see the HTTP request/response headers (thanks for that!). What I've noticed is that unnecessary authentication calls are being repeated. This may be an artifact of the application's internals and multiple connections, but Cyberduck only needs to authenticate once. The X-Auth-Token returned by a successful authentication can be used for each connection to the storage or CDN systems. Also, the URLs to the storage and CDN systems do not change between requests, so that information can be cached and re-used between each connection.
So what I expected to see in the Log Drawer was one connection to https://api.mosso.com/auth with appropriate headers. The response's X-Auth-Token, X-Storage-Url, and X-CDN-Management-Url can be cached and re-used for each subsequent connection.
Be warned that the token will expire over time (possibly as short as an hour). The application should trap a 401 (Unauthorized) response on a given request (to either storage or cdn system) and then re-authenticate to obtain an updated token.
