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..
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.
config_db() and interaction_data() are as defined in Inets
Users Guide.
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..
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..
