I am planning to develop a project which will have access to different services placed in different domains using ajax, so that it may get different types of data from each of them.
At the beginning I thought that due to cross-site scripting that can't be done so I would have to use a different approach or maybe use a bridge (make the calls to my server which will behind the scenes call the others) but the bridge would become a performance issue.
But then I was testing Angular using Google's API and realized that it just works. I mean, I could make AJAX calls to my localhost (though I know localhost may work just because it's localhost) using a script loaded from googleapis.com.
Now I wonder if it is possible or not to have a page with ajax calls to other domains like: mail.mydomain.com, profiles.mydomain.com, media.mydomain.com, and so on. And if so, can that be done just like that or are there any limitations? Because I remember that some years ago I had trouble doing things like that due to the cross-script block.
Just in case it helps, I'm planning to use Angular to get the data and paint it over the views.
Thanks.
Yes, it has limitations, but can be relieved easily. Set HTTP header "Access-Control-Allow-Origin" to "*" does it.
