Oh replying to myself just to add a little bit, Andre, in my own software when I need to check for network connection, I do like you but I get url from my own server, I am aware of the shortcommings of this method but as a matter of fact, all I usually want to know is that if I am able to communicate with my own server, so even if the software hangs for a while, it is ok for me.
I just said the quotes on the previous email because people here have developed better solutions th an the one you and I are using, but what you did and what I use work as well for our needs.
