Logging into a remote system through ajax and setting cookies

Question

I am working on an application that pulls in information from another one and iframes it in mine. I need to be able to authenticate off the other system.

It was/is working using a jQuery submit to a hidden form, but timing issues are making it tricky.

What I would like to do is an ajax post to the other system and have the cookies set so on ajax completion I can transfer them to another page.

My code currently looks like this:

$(document).ready(function() {
    $.post('Anotherserveronasubdomain.com', {
        username : '<?php echo $username ?>',
        passowrd : '<?php echo $password ?>',
        action : 'logon'
    }, function(data) {
        alert(data);
        //$(location).attr('href', 'apagewiththerightinformationifcookiesareset.php');
    }); 

});

That script doesn't return anything and therefore cookies aren't set. Is there a way to have the remote system set those cookies or am I running in circles here?

Thanks for your time.

Answer 1

Are you in control of that site on the other subdomain? If the cookies are set with ".domain.com" they will be valid for all sub-domains, and this should work.
