===== Directory index files =====
{{Main|Web server directory index}}

If a web server program receives a client request message with an URL whose path matches one of an existing ''directory'' and that directory is accessible and serving directory index file(s) is enabled then a web server program may try to serve the first of known (or configured) static index file names (a [[#Regular files|regular file]]) found in that directory; if no index file is found or other conditions are not met then an error message is returned.

Most used names for static index files are: <code>index.html</code>, <code>index.htm</code> and <code>Default.htm</code>.
