http-replay

A Node.js tool for executing HTTP activity on a timed basis. Useful for e.g. replaying log files to simulate real traffic.

Usage:

$ node http-replay.js my-config.json

The my-config.json file specifies the requests that should be executed:

{
    "base_url": "http://simonwillison.net/",
    "requests": [{
        "offset": 0,
        "path": "/about/",
        "method": "GET"
    }, {
        "offset": 3,
        "path": "/",
        "method": "GET"
    }, {
        "offset": 7,
        "path": "http://www.postbin.org/y525h3",
        "method": "POST",
        "data": {"foo": "bar"}
    }]
}

The "offset" key allows you to time your requests - in the above example, a GET request well be made to /about/ as soon as the tool is run, a request to / will take place 3 seconds after launch and a POST to postbin will happen 4 seconds after that (7 seconds total since the tool was started).
