[jQuery] $.ajax success/error callback arguments, textStatus?


reference: http://docs.jquery.com/Ajax/jQuery.ajax#options
What exactly is textStatus of the success and error callback argument?
Being a coldfuision user, I tried:
<cfheader statuscode="403" statusText="testing123">
However, the textStatus is always the default value.
Any idea how to set textStatus on the server side? Thank you!
