NAME
mod_alias - URL aliasing.
DESCRIPTION
Erlang web server internal API for handling of, for example, interac-
tion data exported by module mod_alias.
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 User's Guide.
path(PathData, ConfigDB, RequestURI) -> Path
Types:
PathData = interaction_data()
ConfigDB = config_db()
RequestURI = 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 Inets
User's 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 Con-
figDB, 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 Short-
Path as an argument. config_db() is the server config file in
ETS table format as described in Inets User's 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_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.
