+Configuring httpd with {erl_script_alias, {"/d", [httpd_inets]}} and
+compiling httpd_inets.erl will make the following URL refer to
+httpd_inets:hello/3:
+
+ https://localhost:8080/d/httpd_inets:hello
+
+Here's an example of what http_inets.erl can look like:
+
+$ cat httpd_inets.erl
+-module('httpd_inets').
+-export([hello/3]).
+
+hello(SessionID, _Env, _Input) ->
+ mod_esi:deliver(SessionID, [

+httpd config 'modules' seems to be crucial to get right, including the
+order of the modules listed. The mod_esi module is the one providing
+the erl_script_alias functionality. Here's a configuration that's
+working with Erlang R15B01 (erts-5.9.1):
+
+ {modules, [mod_alias,
+ mod_auth,
+ mod_esi,
+ mod_get,
+ mod_head,
+ mod_log,
+ mod_disk_log]},
