I think pipelining would allow more than one stream from HTTP to be loaded at a time. So for example it might better handle loading from two pages at once. I really don't know just my guess from the names. Pipeling in computers usually means some form of concurrency.
- HTTP requests and responses can be pipelined on a connection.
Pipelining allows a client to make multiple requests without
waiting for each response, allowing a single TCP connection to
be used much more efficiently, with much lower elapsed time.
