Use a GOPROXY for a specify path/domain

[Pierre Durand]

At my company we use an internal Go proxy in order to access private dependencies.

Our Go proxy manages the authentication to our dependencies repositories.

So my config looks like this:

GOPROXY='https://goproxy.mycompany.com,direct'

Unfortunately, our proxy is slightly slower than the public Go proxy for public dependencies (github, etc...)

So I would like to use the public Go proxy for public dependencies, and our internal Go proxy for private dependencies.

I changed my config to:

GOPROXY='https://proxy.golang.org,https://goproxy.mycompany.com,direct'

It works well, but I think it could cause a small privacy issue: it always send a query to the public Go proxy for our private dependencies.

Is it possible to use a specific Go proxy for a path/domain ?

Something like

GOPROXY='git.mycompany.com=https://goproxy.mycompany.com,https://proxy.golang.org,direct'

(I know this syntax doesn't work)

I think it would be very helpful to be able to configure a Go proxy for some domains/path.
