The Dynamic Federations system allows to expose via HTTP and WebDAV a very fast dynamic name space, built on the fly by merging and caching (in memory) metadata items taken from a number of (remote) endpoints.

One of its fundamental features is to be redirect GET/PUT requests to the site or cluster hosting the requested file that is closer to the client that requested it. The focus is on performance, scalability and realtime fault resilience with respect to sites that can go offline.

From the perspective of a normal user, HTTP and WebDAV clients can browse the Dynamic Federation as if it were a unique partially cached name space, which is able to redirect them to the right host when they ask for a file replica. Dynafed also supports writing. [more]
