Testing AJAX requests across different domains on a local server setting

While working in my local development environment at , I encountered the need to make an Ajax call to open a URL and display the response in fancybox. Due to the local development environment, this creates a cross-domain issue. However, once deployed to the server, this issue no longer exists. I'm seeking advice on how to test my Ajax call locally using tools such as Fiddler. I attempted to use Fiddler and modified the Response Header by adding "Access-Control-Allow-Origin", "*", following the steps outlined in this blog post: . Unfortunately, this approach did not work for me. Can anyone suggest a solution?

Answer №1

The issue at hand is related to the fancybox jQuery plugin, specifically how it sets the request header Access-Control-Request-Header as x-fancyBox.

Despite setting the Access-Control-Allow-Origin as * in the response header, this parameter still fails my Cross Domain call.

I decided to comment out the default value of headers in the fancybox 2.1.4 source code, and after doing so, I was successful in making the cross domain ajax call.

Now I am looking for a way to programmatically modify the headers value. I have attempted a few approaches without success:

1. dataType : 'html', headers : { 'X-fancyBox': false }

2. dataType : 'html', headers : { }
