Do you know any such hosts that rate limit unauthenticated > users? Do their users prefer SSH which always authenticates? At GitHub, we do this with the API, and because Git LFS uses Git's credentials and is technically implemented as part of the API, it applies there as well. I don't know that we have any intention of doing it for Git operations themselves, but the reason we typically prefer authentication is that if there's a problem, it's much easier and a better experience to contact user XYZ and ask them to be more gentle than to block their IP. This is particularly useful for internal users at GitHub (like the automatic dependency updating service, Dependabot), where we'd like to account for who's performing lots of operations in terms of rate limiting, and the alternative is that people use http.extraHeader or a token in the URL, neither of which we want to encourage. I'd much rather rate-limit an internal service which is using too many resources than impact unrelated users, but if they're all anonymous, that's hard. > > I intend to add this feature at some point relatively soon, but I need > > to sneak in a feature first to specify the authentication scheme as part > > of the credential protocol, since we won't have it as part of the HTTP > > 401 response. > > Would it suffice to ask the user to specify the authentication scheme > in the configuration? eg. `http.alwaysAuth=basic` or > `http.alwaysAuth=digest` That will probably work for most cases, but we may need to allow either a scheme or a full WWW-Authenticate header, since in some cases there may be parameters that are needed. -- brian m. carlson (he/him or they/them) Toronto, Ontario, CA
