type Handler

type Handler struct {
	Next  middleware.Handler
	Root  string // must be absolute path to site root
	Rules []Rule

	// These are sent to CGI scripts in env variables
	SoftwareName    string
	SoftwareVersion string
	ServerName      string
	ServerPort      string

type Rule

type Rule struct {
	// The base path to match. Required.

	Ext string

	// The path in the URL will be split into two, with the first piece ending
	// with the value of SplitPath. The first piece will be assumed as the
	// actual resource (CGI script) name, and the second piece will be set to
	// PATH_INFO for the CGI script to use.
	SplitPath string

	// If the URL does not indicate a file, an index file with this name will be assumed.
