HTTP-Pipelining

HTTP pipelining is a technique in which multiple HTTP requests are passed to a single socket without waiting for a response. Pipelining is only supported by HTTP/1.1.

Especially in high-latency connections, such as Internet access via satellite or the multi- forwarded connections via the anonymizing Tor network, this results in a considerable shortening of the page load times with it. When web browsing via Tor makes the filter proxy default and Polipo use of it.

Since pipelining is not supported by any server, this is not used in queries for a new connection because it could not be determined whether the server supports HTTP/1.1.

This pipelining works, both the server and the client must support pipelining. Servers that support HTTP/1.1 pipelining support at least in so far as relevant inquiries do not lead to errors.
