JS security issue with Opera 11.01, after moving from server A to B
问题 I have a outer HTML-document (subdomain1.server-a.de) with an iFrame and inner HTML-document (subdomain2.server-a.de). The inner script should send & receive AJAX-requests to subdomain2.server-a.de. I've set the document.domain-value for both documents to "server-a.de" - so far, so good, works well in all tested browsers (FF/Chrome/Opera). Now I move the scripts to server-b.de with same subdomains and set the document.domain on both documents to "server-b.de". That still works in FF and
