XDomainRequest is not supported. No URLs are rewritten for this object. This leads to 'Access denied' errors in case of portal access if the client uses Microsoft Internet Explorer version 8 or version 9.
Cross-domain requests fail with 'Access denied' error.
This occurs in web application that use XDomainRequest for cross-domain requests, when the client uses Microsoft Internet Explorer version 8 or version 9.
To work around this issue, replace the XDomainRequest object with XMLHTTPRequest object using an iRule. Doing so is typically safe because in the case of portal access, web applications do not use cross-domain requests. The only restriction is when the XDomainRequest object includes the 'contentType' property, which is not supported by XMLHTTPRequest object.
XDomainRequest is supported similar to XMLHTTPRequest.
