I am getting the strange error \"SCRIPT70: Permission denied jquery.js, line 21 character 67\" on IE-9. Searched on google but could not find anything except a
The SCRIPT70 error in IE9 occurs most likely when your iframe is calling some javascript (especially if it affects the parent page - e.g. hash change of parent url)
Check that your iframe's host/protocol/port number matches. IE9 is exceptionally strict about the host name(down to the www portion in my case) and document.domain did not seem to provide a workaround for that.
Encountered this issue and fixed it while dealing with multiple iframes, hope this helps others with the same issue.
