Hello all, I''m trying to get (using Ajax) whatever URL the user clicks on the page. Also, I want to store the results from the URL request in a JS variable. Did somebody know helper in Rails which allow me to do that ?

Well, I have found some interesting code :
(http://prototypejs.org/learn/introduction-to-ajax)
#
new Ajax.Request(''/some_url'',
{
method:''get'',
onSuccess: function(transport){
var response = transport.responseText || "no response text";
alert("Success! \n\n" + response);
},
onFailure: function(){ alert(''Something went wrong...'') }
});
##
But, instead of using ''/some_url'', I would like to use
''http://
a_different_domain.com..."
According to the "Prototype" library website :
"Ajax requests can only be made to URLs of the same protocol, host and
port of the page containing the Ajax request"
-> does somebody know if it''s only a "Prototype" library
restriction,
or if it''s a restriction for Ajax in general ? if it''s not,
somebody
have an idea to make it work ?
Thanks
Thib

Not sure, but I think it''s a general restriction of XMLHTTPRequest in browsers in order to avoid security loopholes. It would be too easy if this were possible to have a user submit information to other websites without them knowing. Dirk.

It is indeed a javascript security restriction for the reason mentioned below. The best solution is to submit the request to your server and have the server fetch the page and process it (send it back as a response). And usually it''s a good idea to cache those offsite fetched responses.
