- Rename SessionState to State to avoid stutter. - Simplified option validation to use a wrapper function for base64 secrets. - Removed authenticates grpc code. - Abstracted logic to load and validate a user's authenticate session. - Removed instances of url.Parse in favor of urlutil's version. - proxy: replaces grpc refresh logic with forced deadline advancement. - internal/sessions: remove rest store; parse authorize header as part of session store. - proxy: refactor request signer - sessions: remove extend deadline (fixes #294) - remove AuthenticateInternalAddr - remove AuthenticateInternalAddrString - omit type tag.Key from declaration of vars TagKey* it will be inferred from the right-hand side - remove compatibility package xerrors - use cloned http.DefaultTransport as base transport
