Aza,
I think you got confused.
ESL and mod_xml_curl are not doing the same thing.
ESL is a way to control FreeSWITCH through the even socket (you can send commands like call this number, listen to DTMF, play audio file, etc...).
Mod_xml_curl is "just" a way to have your config, dialplan and directory stored in a DB, that FS will access through a HTTP/XML middleware.
You can't write applications with that.
The alternative to ESL is to use scripting in the dialplan (mod_lua, mod_python, etc...). A such application is generally put somewhere in the dialplan, so it is triggered because FS executes an extension.
You can also execute it from CLI (with luarun for instance).
As you say that you want to write a web-based app, I guess you should go for php/ESL.
Playing with that, you will perhaps find exactly what suits you.
To install php/ESL support, you need to compile FreeSWITCH with:
./configure --with-php
make install
and after that:
cd libs/esl
make phpmod-install
(php-devel is a required package)
