ExeOutput, external call with Ajax

Hello everyone,
I have a problem with Exeoutput and I do not understand its origin.
The result is essentially an html page with JQuery, making ajax calls to an external server.
The call is made with http://www.domainname.ext/filename.php
If I type the address directly in the customer’s browser the page is successfully achieved …

On external server (Apache) I configured the CORS with:
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Credentials: “false”

It works on MY computer BUT NOT on customer PC: practically does not reach the server.

The customer has Windows 7 with IExplorer 8.

I checked the host file, compatibility mode, on my computer and on that of the customer: I did not find anything …

What could it be?

Maybe the customer has a firewall that prevents the EXE to access the requested page?

Absolutely no firewall (hw or sw): connecting my laptop to the same network, the program runs smoothly. I still think that the problem is the CORS and the customer’s Explorer version limits . I also applied the JQuery plugin https://github.com/MoonScript/jQuery-ajaxTransport-XDomainRequest but does not solve. I do not know what to check … Mhmhmh: I could give a different computer to the customer!

Check that your jquery version supports IE8. Some recent versions don’t.

Thank you for the support… It’s true: 2.x versions of JQuery don’t support IE8 but I use jquery-1.10.1 so it should work…
Today I try to write a part of the program using XDR, hoping to solve

You could also try to use PHP to retrieve contents from your remote script. This will help us to know whether it’s a AJAX limitation or a connection problem.
