HTTP Pipeline Surveyor

HTTP pipelining brings attractive performance improvements, but it can be a dangerous business on the open Internet.

This script demonstrates one method of checking an HTTP connection to see if pipelining is safe on a given connection. It is ONLY intended to discover problems with errant intermediaries (e.g., "transparent" proxies); it doesn't assure that the servers you contact will correctly support pipelining.

It's a work in progress. For more information, see the associated Internet-Draft.

Installation

First you'll need Node and its package manager, npm.

Then, it can be installed with npm like this:

npm install pipeline-surveyor

Use

Just call it on the command line;

pipeline-surveyor

and it will report back "OK" if it thinks HTTP pipelining is usable on your current connection. If not, it will say "FAIL", followed by a description of the problem it encountered.

Running the server

The server-side can be run using node.You'll still need to have the npm package installed.
