Download Mode File - Exclude Everything, Then Whitelist

[damnski]

Hello,

I have use case question for the Download Mode File (https://docs.gomods.io/configuration/download/). We'd like to exclude everything, then whitelist only certain modules. Is this possible? If it is possible, another side effect is how to add this to the use cases in the documentation?

Thank you,
Best,

hey @damnski ! it is possible, here's a simple example of a Download Mode File:

downloadURL = "https://proxy.golang.org"

mode = "sync"

download "company.com/allow/a" {
    mode = "sync"
}

download "company.com/allow/b" {
    mode = "sync"
}

download "company.com/allow/*" {
    mode = "none"
}

In the download mode file above, only company.com/allow/a and company.com/allow/b will be whitelisted.

However, do note that even downloads are restricted, the /list and /latest handlers will still return data to the proxy user. I'm not sure if this is intended but just a note here.
