Overview

Rack middleware that will serve GridFS files from a specified path prefix. By default the prefix is stripped from the path before file lookup in GridFS occurs.

For example:

"/gridfs/filename.png" -> "filename.png"

If you are using Rails you can mount the endpoint directly.

For example (in config/routes.rb):

mount Rack::GridFS::Endpoint, :at => "gridfs"
