+Subject: [PATCH] inets: Check script_alias when using mod_auth
+
+- Update mod_alias: which_alias() now also returns script_alias entries so mod_auth checks directories against real script locations.
+- Add explanatory note in httpd.xml under script_alias about using real filesystem paths for directory-based authentication when script_alias is used.
+- Add comments in mod_alias.erl clarifying behavior with mod_auth.
