type Cache ¶

type Cache struct {
	// Time for which a answer is held im memory. A TTL <= 0
	// makes the Cache pass all requests directly to the handler.
	TTL time.Duration
	// Handler, whose responses are supposed to be cached
	Handler http.Handler
	// Maximum number of bytes, with which an response is eligible
	// for caching (default: 20MiB)
	MaxCacheableSize int64
	// contains filtered or unexported fields
}

Cache is a `net/http.Handler`, which uses `net/http/httptest.ResponseRecorder` to record and recall the responses of the wrapped handler from memory if the same URL is requested again. The `net/http.Request.URL.Path` is used as the caching key.

func NewCache(d time.Duration, handler http.Handler) *Cache

func (ch *Cache) ServeHTTP(w http.ResponseWriter, r *http.Request)

type GridDir ¶

type GridDir struct {
	GridFS *mgo.GridFS
	// If true, the leading slash will be stripped from requests
	StripSlash bool
}

GridDir implements net/http.FileSystem to serve contents directly from MongoDB's GridFS.

To serve all files from a database containing a GridFS called `fs` via http:

session, err := mgo.Dial("mongodb://localhost/database")
if err != nil {
    log.Fatalf("Could not connect to mongodb: %s", err)
}
gfs := session.DB("").GridFS("fs")
http.Handle("/", http.FileServer(sabercat.GridDir{gfs})

Directory listing has not been implemented.

func (gd GridDir) Open(filename string) (http.File, error)
