An HTTP (or HTTPS) based remote server may now offer a 'clone.bundle' file in each repository's Git directory. Over an http:// or https:// remote repo will first ask for '$URL/clone.bundle', and if present download this to bootstrap the local client, rather than relying on the native Git transport to initialize the new repository. Bundles may be hosted elsewhere. The client automatically follows a HTTP 302 redirect to acquire the bundle file. This allows servers to direct clients to cached copies residing on content delivery networks, where the bundle may be closer to the end-user. Bundle downloads are resumeable from where they last left off, allowing clients to initialize large repositories even when the connection gets interrupted. If a bundle does not exist for a repository (a HTTP 404 response code is returned for '$URL/clone.bundle'), the native Git transport is used instead. If the client is performing a shallow sync, the bundle transport is not used, as there is no way to embed shallow data into the bundle.
