Types

type HTTPIngressPath

type HTTPIngressPath struct {
	// Path is an extended POSIX regex as defined by IEEE Std 1003.1,

	// contain characters disallowed from the conventional "path"
	// part of a URL as defined by RFC 3986. Paths must begin with
	// a '/'. If unspecified, the path defaults to a catch all sending
