localpath

)

Creates an local filesystem handler.

Creates an export local handler. When path matches, it returns a file from localpath (final localpath + path). No dir listing.

Exports the given localpath and any file inside this localpath is returned.

It performs security checks, so that the returned data is saftly known to be inside that localpath. Normal permissions apply.
