Modeled so that it provides a subset of the requests interface.
This has been created so that it does only provide a minimal API for our
needs. The parts which it provides are based on the API of the library
`requests` which allows us to easily benchmark against it.
Please have a look at the class :class:`requests.Session` when you extend

`requests` as a drop in replacement for benchmarking purposes.
