What is the best method for testing an AJAX application that fetches data from a live website?

I'm currently developing an AJAX application that retrieves data from a live website. Unfortunately, I am unable to replicate the entire application on my local environment at this time. In order to test whether the JavaScript code is functioning correctly, I need to find a way to bypass the same domain restriction in the browser without making alterations to the web server. Any suggestions would be greatly appreciated.

Thus far, I have attempted to modify the prefs.js file in Firefox 2 and Camino as well as following the instructions provided in this link:

Thank you in advance.

Edit 04/29/2009 3:18pm:

I understand that using a proxy is a viable option. However, I am wondering if it is possible to find a solution using only Firefox (perhaps through an add-on)?

Answer №1

One potential solution is to modify the endpoint URL in order to route requests through your local server using either mod_rewrite or a custom script.

This approach offers the benefit of being able to efficiently track both incoming requests and outgoing responses, allowing for modifications such as returning timeout errors or manipulating data if needed.

Answer №2

If you want to easily view requests and step through JavaScript, I recommend using Firebug.
