Query about setProxy() function

[sups]

Hello,

I have some problem in using qt setProxy() function.
I have to download file from a http server which I have installed on another system .
I have installed apache2 server and squid proxy server installed on that system.

what address should i provide for setproxy() function and what port.

How can I know that my code is working or not.

Here is my code.
