The requested file cannot be served: does not exists, not enough permissions ...
exception Failed_403
The file is a directory which we should not display
exception NotReadableDirectory
type resolved = | RFile of string | RDir of string
Local file corresponding to a request. The string argument represents the real file or directory to serve, eg. foo/index.html instead of foo

request:Ocsigen_extensions.request ->
filename:string -> unit -> resolved
Finds filename in the filesystem, with a possible redirection if it is a directory. Takes into account the fact that filename does not exists, is a symlink or is a directory, and raises Failed_404 or Failed_403 accordingly.
- we return "filename/index.html" if filename corresponds to a directory, "filename/index.html" is valid, and "index.html" is one possible index (trying all possible indexes in order)
- we raise Failed_404 if filename corresponds to a directory, no index exists and list_dir_content is false. Warning: this behaviour is not the same as Apache's but it corresponds to a missing service in Eliom (answers 404). This also allows to have an Eliom service after a "forbidden" directory
- we raise Failed_403 if filename is a symlink that must not be followed
- raises Failed_404 if filename does not exist, or is a special file
- otherwise returns filename
no_check_for is supposed to be a prefix of filename ; directories above no_check_for are not checked for symlinks

Given the local file file, with a request originating at url url, returns a viewable content of file. Currently, the url parameter is used only if url is a directory
