I have built a webshop in rails, now it’s time for invoice handling
through a third party. The communication will be done by xml-rpc. The
built in ruby xml-rpc doesnt seem to be compatible with the third party
so I have to use a special php-script (provided by the third party) that
will handle the interaction with them. Where on the server should/can I
put the script? I would prefer to have it in railsapp/app or
railsapp/public, but that doesnt seem to work.
