inetc::post?

[phisuio]

Hi,
I simply want to open this website: "www.example.com/index.php?username=$username"
so I am trying to do it using the inetc-component, this is my source:

...
inetc:: post "http://www.example.com/index.php?username=$username" "http://www.example.com/index.php?"
Pop $0
MessageBox MB_OK $0

The messagebox says: "connecting", but as I can see on the server, it doesn't work, when using "get" instead of "post" it gives the error message: "File Write Error", but it seems to work as I can see on the server.

So I need to make it say "OK" when it worked on the server, any idea?
Thanks!
