Hi, Kinga...
Thanx for taking time to talk about this. But so far,
that solution's not working either. Just a quick question
- does the contents of the postData need to be of the form
"?foo=data" and does the data segment need to be url
encoded?
I've put your suggestions in and so far, the server hangs
- it never responds back - and doesn't even act like it's
been queried... kinda strange...
again, many thanx...
peace. JOe...
