You won't be able to do a cross-domain POST request in the browser.

If you are making a JSONP call to access a cross-domain URL, you can use JQuery's getJSON method. This would allow you to make a GET request only. If you can submit your login information to the redirectURL using GET parameters, you could make this work.

Note that POSTing to remote login forms is perhaps the best example of why browsers disallow cross-domain requests like this. You don't want a page that looks like your bank to be able to actually serve you data from your bank's website -- that would make a very effective phishing page.

On the other hand, if you really want to work around this, you can write some server-side code that, given the input parameters, makes a post request to the redirectURL and funnels back the response.

Please tell me you are not writing a phishing page.
