• ajax cross-domain requests

  - by yoda

  Hi, Since Ajax requests are limited for security reasons, there's not much to it, just follow the rules eh .. but I've crossed with this : https://developer.mozilla.org/en/Same_origin_policy_for_JavaScript It's written that you can "bypass" those rules, in case you're working with subdomains of the same domain, with the following javascript line : document.domain = "company.com"; I haven't tried it yet, since I don't know if this only works (perfectly works) with any other browser, or at least the major ones. Is it possible? Thanks.
