I remember reading somewhere that JavaScript can only contact back to the
server that It was loaded from... 

As far as reverse engineering your ajax calls... sure... but how is it
different from reverse engineering html and changing hidden fields, etc...
As long as you're doing proper authentication when you process the call, and
validating the data (not letting javascript do it for you), you shouldn't
have any security problems.

Subject: AJAX and security

It has just hit me that AJAX may not be all that safe.

One could derive all that is being passed in an AJAX request by using view
souirce and nabbing any included JS files.  Once you had that info you could
then figure out what's being sent in the request (i.e. variable names etc.).

So in the case of an AJAX call that perhaps sends form contents to be
inserted into the DB....what's to stop someone from reverse engineering your
AJAX call and start inserting their own data??

I'm not readily seeing in the AJAX code where the domain is specified (my
guess is programatically) as there is no domain setting....just which
CFC/CFM file to call.

I'm still working out the kinks....I love the possibilities of
CFAJAX.....but this security issue (if it really is one) has me a bit
spooked ;-)

TIA
