[jQuery] Issue building an AJAX form with the Form plug-in - can you post to a page on sub-domain?


I build an AJAX form that uses the default Form plug-in. The form
resides on an XXX.myserver.com and it's posting to an action page on
YYY.myserver.com. When I test the page and submit the form, I get
directed to the action page. If I put the action page on
XXX.myserver.com and change the code to reflect that..., the page
works and the form is reset.
Is there something that I am missing?
