# cleanhttp

Functions for accessing "clean" Go http.Client values

-------------

The Go standard library contains a default `http.Client` called

`http.DefaultClient`. It is a common idiom in Go code to start with

`http.DefaultClient` and tweak it as necessary, and in fact, this is

encouraged; from the `http` package documentation:

> The Client's Transport typically has internal state (cached TCP connections),

so Clients should be reused instead of created as needed. Clients are safe for

concurrent use by multiple goroutines.

Unfortunately, this is a shared value, and it is not uncommon for libraries to

assume that they are free to modify it at will. With enough dependencies, it

can be very easy to encounter strange problems and race conditions due to

manipulation of this shared value across libraries and goroutines (clients are

safe for concurrent use, but writing values to the client struct itself is not

protected).

Making things worse is the fact that a bare `http.Client` will use a default

`http.Transport` called `http.DefaultTransport`, which is another global value

that behaves the same way. So it is not simply enough to replace

`http.DefaultClient` with `&http.Client{}`.

This repository provides some simple functions to get a "clean" `http.Client`

-- one that uses the same default values as the Go standard library, but

returns a client that does not share any state with other clients.
