how can i test HTTPS POST in saucelabs?

I have tested on saucelabs before

But now, i have to test IE8 and IE9 which does not support XMLHttpRequest.

IE8,9 only support XDomainRequest which does not support CORS between HTTP and HTTPS (Links here)

I am using Karma+Jasmine+Saucelabs.

Is there any way that i can test on HTTP Server?
