HTTP server benchmarking/load testing in Python

[Dino]

Hello, I could use something like Apache ab in Python ( 
https://httpd.apache.org/docs/2.4/programs/ab.html ).

The reason why ab doesn't quite cut it for me is that I need to define a 
pool of HTTP requests and I want the tool to run those (as opposed to 
running the same request over and over again)

Does such a marvel exist?

Thinking about it, it doesn't necessarily need to be Python, but I guess 
I would have a chance to tweak things if it was.

Thanks

Dino
