QHttp has problems with some url's

[whoops.slo]

Hi!

I tried example programm from Qt's "Examples and Demos" from section Networking - HTTP Client. I mdified it so it does not look for file name from the URL I give as input. If I try several addresses I download the main file (usually index.php, but I modified the saved file as index.txt for easier reading the content) but I can not get it from this address: "http://www.ednevnik.si/?w=malea" There is somekind of redirection that QHttp can not comprehand. The Error say: "Found". Can some of you take a look of the situation and help me with this matter? When I try to download the file from URL "http://www.rozina.si/6pack/" I receive empty file. It seems to be the problem with all blogs from address www.rozina.si as well as with all blogs from www.ednevnik.si. But a friend that is using PERL was able to get the file from those adresses. Can any of you find an explanation for this? What is happening? I can not explain the failure.
The attached file should be renamed cpp and is modified file of the Qt's example...

Regards!
Luka

I'm not sure about the latter url, but you can get at least contents of "http://www.ednevnik.si/?w=malea" by changing:

httpGetId = http->get(url.path(), file);

httpGetId = http->get(url.path(), file);

To copy to clipboard, switch view to plain text mode 

to:

httpGetId = http->get(url.toString(), file);

httpGetId = http->get(url.toString(), file);
