CommonHeader is an enum of the most common HTTP headers

enum Method {
	get
	post
	put
	head
	delete
	options
	trace

enum SameSite {
	same_site_default_mode = 1
	same_site_lax_mode
	same_site_strict_mode
	same_site_none_mode
}

SameSite allows a server to define a cookie attribute making it impossible for the browser to send this cookie along with cross-site requests. The main goal is to mitigate the risk of cross-origin information leakage, and provide some protection against cross-site request forgery attacks. See https://tools.ietf.org/html/draft-ietf-httpbis-cookie-same-site-00 for details.

The status codes listed here are based on the comprehensive list, available at: https://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml

fn (code Status) str() string

fn (code Status) int() int

int converts an assigned and known Status to its integral equivalent. if a Status is unknown or unassigned, this method will return zero

fn (code Status) is_valid() bool

is_valid returns true if the status code is assigned and known

fn (code Status) is_error() bool

is_error will return true if the status code represents either a client or a server error; otherwise will return false

fn (code Status) is_success() bool

is_success will return true if the status code represents either an informational, success, or redirection response; otherwise will return false

enum Version {
	unknown
	v1_1
	v2_0
	v1_0
