Hi franck, I guess you need add a reason as to why this method is
needed. As I said, once it didn't work, I just used get, and that
worked well. As far as the server (Dancer) is concerned, an incoming
call is either a get/post/delete, etc. The ajax-ness of it is that it
has been initiated as an ajax requested, and that is a client side
issue. So, I use jQuery to make a call, and that call comes to the
server as a get request. So, why is the ajax method needed on the
server? What does it do that get can't or won't do?
