Submit 1 form on 2 locations ?

[robix]

Is it possible to submit a form on 2 different websites ... ? For example; when user types his "name" and "last-name" in the form and clicks submit button.. it first gets submitted to main site and then the same data gets submitted to an external site which is having same "name" and "last-name" as an input box and a submit button....

Thanks,
Robin
