If you have a proxy you will need to start with this command
$ export http_proxy=http://100.1.1.1:8080
And then you just need to call the site
$ wget -O-
http://www.google.pt
The result should be like this - getting all the HTML page:
--12:37:20--
http://www.google.pt/
Connecting to 100.1.1.1:8080... connected.
Proxy request sent, awaiting response... 200 OK
