Functions ¶
func BuildInfoAsHtmlFunc ¶
func BuildInfoAsHtmlFunc(bi BuildInfoer) func() template.HTML
Forced into this API to make it easily invocable by template
func CanonicalizeHandler ¶
func CanonicalizeHandler( logger *slog.Logger, domainCanonicalizer RedirectFunc, pathCanonicalizer RedirectFunc, next http.Handler, ) http.Handler
func FlyInfoAsHtmlFunc ¶
Forced into this API to make it easily invocable by template
func GenBase32Etag ¶
Base64 uses '/' and '+' chars and I'm not sure '+' is valid for ETAGs, so we use Base32 to cut risk
func GetGitInfo ¶
func GetGitInfo() string
func GetRequestIdOrDefault ¶
func RecoverPanicHandler ¶
func RewriteHandler ¶
func RewriteHandler( logger *slog.Logger, rewrite map[string]string, next http.Handler, ) http.Handler
Transparent internal rewrites
func SecurityHeadersHandler ¶
XXX As written, attacker may be able to potentially exhaust random pool!
Types ¶
type BuildInfoer ¶
type BuildInfoer interface {
GitRevision() string
}
type RedirTarget ¶
type RedirectFunc ¶
Returns "to" URL and redirection code if redirection warranted Returns code==0 if no redirection indicated
func DomainCanonicalizer ¶
func DomainCanonicalizer( logger *slog.Logger, canonFQDN string, secondaryFQDNs []string, ) RedirectFunc
Should probably only be invoked in local/dev mode and not production Returned func returns (nil, http.StatusBadGateway) on error
func PathCanonicalizer ¶
func PathCanonicalizer( logger *slog.Logger, redirMap map[string]RedirTarget, ) RedirectFunc
Redirect old URLs picked up by search engines
type ServerWithShutdown ¶
