I am trying to make Erlang's Inets mode_esi work and run some function. So, far, I did not succeed. Can someone post a minimal example of how to run Inets so that a url like http:localhost:8099/esi/my_mod:foo will invoke the method my_mod:foo/3?
Addition: I have started inets with these commands:
inets:start(),
inets:start(httpd, [{port, 8099}, {server_name, "localhost"}, {document_root, "."},
{server_root, "."}, {erl_script_alias, {"/esi", [my_esi, io]}}]).
The module is:
-module(my_esi).
-export([foo/3]).
foo(Sid, Env, In) -> mod_esi:deliver(Sid, ["bla"]).
But browsing to http://localhost:8099/esi/my_esi:foo result in an error message.
I've solved it myself. For some reason, beyond my understanding, the exact same code worked when I invoked Inets with a configuration file (a modified version of inets/examples/server_root/conf/8080.conf). I suppose that the example file includes a more complete list of properties that Inets required than what I listed in inets:start(httpd, [...]). If anyone encounters Inets problem in the future, my advice is to start with the example configuration.
