Hello David,
Thank you very much for the help. I tried to apply the patch atttached but
ran into some errors. Later I resorted to achieve it by using
QNetworkAccessManager, as told by you.
Thank you once again. :)

Judging by the Location header in the reply you expect, KIO::get is<br>
automatically redirecting the request, which is, I think, a very good<br>
thing (the one time I wanted to use KIO::get I wanted to do exactly<br>
that). You then need to go with something more basic, like<br>
QNetworkAccessManager's head method to get the headers and do nothing<br>
more. The attached patch against your sources achieves that (assuming<br>
you have an error on the URL in the code).<br>
