View Source mod_alias (inets v9.3)
URL aliasing.
Erlang web server internal API for handling of, for example, interaction data
exported by module mod_alias.
Summary
Functions
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 User's Guide.
path/3 returns the 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. config_db() and interaction_data() are as defined in
Inets User's Guide.
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, 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's Guide.
real_script_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,
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 User's Guide.

-spec default_index(ConfigDB, Path) -> NewPath when ConfigDB :: ets:tid(), Path :: string(), NewPath :: string().

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

-spec path(Data, ConfigDB, RequestURI) -> Path when Data :: [{real_name, {Path, AfterPath}}], ConfigDB :: ets:tid(), RequestURI :: string(), AfterPath :: string(), Path :: string().
path/3 returns the 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. config_db() and interaction_data() are as defined in

-spec real_name(ConfigDB, RequestURI, Aliases) -> ReturnPath when ConfigDB :: ets:tid(), RequestURI :: string(), Aliases :: [{FakeName, RealName}], ReturnPath :: {ShortPath, Path, AfterPath}, FakeName :: re:mp() | iodata() | unicode:charlist() | string(), RealName :: string(), ShortPath :: string(), Path :: string(), AfterPath :: string().

-spec real_script_name(ConfigDB, RequestURI, ScriptAliases) -> ReturnPath | not_a_script when ConfigDB :: ets:tid(), RequestURI :: string(), ScriptAliases :: list() | [{FakeName, RealName}], ReturnPath :: {ShortPath, AfterPath}, FakeName :: re:mp() | iodata() | unicode:charlist() | string(), RealName :: string(), ShortPath :: string(), AfterPath :: term().
real_script_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,
ShortPath and AfterPath, as defined in httpd_util:split_script_path/1.
