I have two domain names that point to my website, nathannifong.com, and uncc.ath.cx.
Javascript on the site occasionally needs to pull down resources with XMLHttpRequest. All URLs of resources in client scripts refer to nathannifong.com, and when a user comes to the site by uncc.ath.cx, the scripts fail because of cross domain secuity policy in JavaScript.
What should I change so that users can come to the site by any domain name, but the XMLHttpRequests still work?
If you are using the Domain Name in the URL’s to make a ajax request, remove it hence the domain is automatically mapped to the one the user is using and you will not have the cross domain issues.
