hi
I'm attempting to build an app then sends a request to a URL and reads the
response it works fine on my test site but when I connect to a real system I
get the text below, I guess its responding to a request from the remote end
if so how do I either tell it to ignore the request and just send the url or
set what its looking for?
If type the same url in the address bar of IE it works without requesting
any permissions!
the code used to send the request is at the bottom.
Help!!!!
