I need to load the login page of another website (different domain), wait for the user to fill it in and submit it, then read the URL/Location/Querystring for a token parameter to my site and close the login page.
Don't want the username or password, only interested in the returned token (http://www.othersite.com/?token=blahblahblah), which will then be passed as a querystring to a page on my domain (http://www.mydomani.com/loadtoken.php?token=blahblahblah).
Currently, a user has to do this in a separate page, copy and paste the token into my page, since these tokens only have a short life, it's somewhat irritating practice, and if it can be done behind the scenes by the site instead it would make it simpler for everyone.
Reading around on iframes, divs and ajax suggest this is not possible due to security policies, cross site scripting, etc.
Is it possible? What should I be looking for or concentrating on, or can you give some examples.
Thanks for your help.
Edit: Should have said, I understand that it's possible to take the username and password and do a POST behind the scenes, but I really want to avoid making the users give my site their login details to another site, for obvious reasons.
