Supports HTTP/1.1 Byte Ranges
HTTP/1.1 clients can request part of the content of an item using byte ranges. Byte ranges are optional for HTTP/1.1 clients and servers, but servers that support it will be able to restart aborted transmissions more easily.
Supports HTTP/1.1 Persistent Connections
The server can keep a connection with an HTTP/1.1 client open for more than a single request, thereby improving browser performance.
