HstsOnPlainHttp(SocketAddr)

HSTS (RFC 6797) was attached to a frontend on a plain-HTTP listener. RFC 6797 §7.2 forbids Strict-Transport-Security on plaintext-HTTP responses; the worker rejects the request rather than ship a non-conformant policy. The TOML loader rejects the same shape at config-load time (command/src/config.rs::ConfigError::HstsOnPlainHttp); this arm catches the same misconfiguration when the request reaches the worker over the IPC channel without going through the TOML path (e.g. via sozu frontend http add).

Trait Implementations

impl Debug for ProxyError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProxyError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProxyError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
