mod_alias(3erl) 					     Erlang Module Definition						   mod_alias(3erl)

NAME

       mod_alias - URL aliasing.

DESCRIPTION

       Erlang Webserver Server internal API for handling of things such as interaction data exported by the mod_alias module.

EXPORTS

       default_index(ConfigDB, Path) -> NewPath

	      Types  ConfigDB = config_db()
		     Path = NewPath = string()

	      If  Path	is  a  directory,  default_index/2 , it starts searching for resources or files that are specified in the config directive
	      DirectoryIndex. If an appropriate resource or file is found, it is appended to the end of Path and then returned. Path  is  returned
	      unaltered, if no appropriate file is found, or if Path is not a directory. config_db() is the server config file in ETS table format
	      as described in Inets Users Guide. .

       path(PathData, ConfigDB, RequestURI) -> Path

	      Types  PathData = interaction_data()
		     ConfigDB = config_db()
		     RequestURI = Path = string()

	      path/3 returns the actual file Path in the RequestURI (See RFC 1945). If the interaction data {real_name,{Path,AfterPath}} has  been
	      exported by mod_alias; Path is returned. If no interaction data has been exported, ServerRoot is used to generate a file Path . con-
	      fig_db() and interaction_data() are as defined in Inets Users Guide .

       real_name(ConfigDB, RequestURI, Aliases) -> Ret

	      Types  ConfigDB = config_db()
		     RequestURI = string()
		     Aliases = [{FakeName,RealName}]
		     Ret = {ShortPath,Path,AfterPath}
		     ShortPath = Path = AfterPath = string()

	      real_name/3 traverses Aliases , typically extracted from ConfigDB , and matches each FakeName with RequestURI . If a match is  found
	      FakeName	is  replaced  with  RealName  in the match. The resulting path is split into two parts, that is ShortPath and AfterPath as
	      defined in httpd_util:split_path/1 . Path is generated from ShortPath , that is the result from default_index/2 with ShortPath as an
	      argument. config_db() is the server config file in ETS table format as described in Inets User Guide. .

       real_script_name(ConfigDB,RequestURI,ScriptAliases) -> Ret

	      Types  ConfigDB = config_db()
		     RequestURI = string()
		     ScriptAliases = [{FakeName,RealName}]
		     Ret = {ShortPath,AfterPath} | not_a_script
		     ShortPath = AfterPath = string()

	      real_name/3  traverses ScriptAliases , typically extracted from ConfigDB , and matches each FakeName with RequestURI . If a match is
	      found FakeName is replaced with RealName in the match. If the resulting match is not an executable script not_a_script is  returned.
	      If   it	is   a	 script   the	resulting  script  path  is  in  two  parts,  that  is	ShortPath  and	AfterPath  as  defined	in
	      httpd_util:split_script_path/1 . config_db() is the server config file in ETS table format as described in Inets Users Guide. .
