http_reply_from_files(+Dir, +Options, +Request)

HTTP handler that serves files from the directory Dir. This handler uses http_reply_file/3 to reply plain files. If the request resolves to a directory, it uses the option indexes to locate an index file (see below) or uses http_reply_dirindex/3 to create a listing of the directory.

Options:

indexes(+List): List of files tried to find an index for a directory. The default is ['index.html'].

Note that this handler must be tagged as a prefix handler (see http_handler/3 and module introduction). This also implies that it is possible to override more specific locations in the hierarchy using http_handler/3 with a longer path-specifier.

Dir

is either a directory or an path-specification as used by absolute_file_name/3. This option provides great flexibility in (re-)locating the physical files and allows merging the files of multiple physical locations into one web-hierarchy by using multiple user:file_search_path/2 clauses that define the same alias.

See also: The hookable predicate file_mime_type/2 is used to determine the Content-type from the file name.
