What's this?

match?(path) public

Takes a path to a file. If the file is found, has valid encoding, and has correct read permissions, the return value is a URI-escaped string representing the filename. Otherwise, false is returned.

Used by the `Static` class to check the existence of a valid file in the server’s `public/` directory (see Static#call).
