    Translate a cURL command created by Chrome's developer tools into a
    command for ``ab``, the ApacheBench HTTP benchmarking tool.

    Parameters
    ----------
    curl_cmd
        The string given to you by the "Copy to cURL" context action in
        Chrome's developer tools.
    num : int
        The number of requests ApacheBench should make in total
    cur : int
        The number of concurrent requests ApacheBench should make

    Note
    ----
    Not all headers play nice with ApacheBench, so ``headers_to_copy`` has
    been set to a reasonable default. Tweak this if you need something
    else in there.

I wasn't expecting google to find something this perfect ❤️

@ctolsen Thanks for sharing! I had to slightly tweak it so that it used my current session (I was testing an authenticated URL)

Neither did I. I guess @ctolson and @google got together earlier and figured that out?

🥇

Helped me a lot so I published it online to be more easy to use.

@ahivert, that is awesome, but please update the output command to take the URL in quotes. Otherwise it blows up in the command line, especially for URLs with parameters like http://foo.bar/path?param1=value2&param2=value2

Thanks @pokrovskyy I fixed it

@ctolsen Thanks for sharing!

@ahivert it doesnt work with POST requests.

❤️ it, thanks!

Forked to add support for POST data using a temp file (Chrome uses --data-binary and --data-raw for POST): https://gist.github.com/odony/93086f5c917e777cb2f4d0c04d477545

@ahivert
